Abstract: Computer Network based problems often require searching a node from another and finding a path from one node to another. To solve this we use graph algorithms. Solving these problems takes a lot of time and knowledge when solved manually. For this purpose graph algorithms where devised and solving these problems became easier but the time taken to solve these problems using the algorithms sequentially takes a lot of time. So to make the time consumed to be less we devised the parallel version of these algorithms and tested. In this paper, we present a new parallel Prim algorithm targeting SMP with shared address space.

Abstract: This paper presents a way to modify the existing Exemplar-Based Image Inpainting. The increased processing time required for this algorithm will be essential to achieve perceptual difference in the quality of filling. The main focus is to better the priority function which will be reflected in the results in contrast to the unmodified algorithm. A new algorithm is planned for removing large objects from digital images. The challenge is to fill in the hole that is left behind in a visually believable way. In ancient times, this type of difficulty has been calculated by two classes of algorithms: (i) "texture synthesis" algorithms (ii) "inpainting" techniques. This paper presents a novel and efficient algorithm that combines the advantages of these two approaches but applied this same algorithm on modified image this gives the good result on one fourth less time to fill the target region.

Abstract: In electronics, adder is a digital circuit that performs addition of numbers. To perform fast arithmetic operations, carry select adder (CSLA) is one of the fastest adders used in many data- processing processors. The structure of CSLA is such that there is further scope of reducing the area, delay and power consumption. Simple and efficient gate - level modification is used in order to reduce the area, delay and power of CSLA. Based on the modifications, 8-bit, 16-bit, 32-bit and 64-bit architectures of CSLA are designed and compared. In this paper, conventional CSLA is compared with Modified Carry select adder (MCSLA), Regular Square Root CSLA (SQRT CSLA), Modified SQRT CSLA and Proposed SQRT CSLA in terms of area, delay and power consumption. The result analysis shows that the proposed structure is better than the conventional CSLA.

Abstract: Multi-agent systems like Peer-to-Peer networks are widely used for content sharing and searching. However, privacy and security are the concerns with such networks as they are vulnerable to attacks due to open, dynamic and anonymous nature. To protect communications over such networks many models came into existence that are based on the reputation or trust of the peers that interact with each other. However, they can not cope with the unpredictable behavior of malicious peers. To overcome this problem and improve QoS (Quality of Service) Das and Islam presented a dynamic trust computation model. In this paper we implement that trust model and build a prototype of multi-agent system to show the proof of concept. The experimental results revealed that the application facilitates dynamic trust computation and achieves secure

Abstract: Distributed Denial of Service (DoS) attacks are widely known attacks on networks that deny service over network. When such attacks use source address spoofing it is not easy to trace the source of attack. This is an open problem to be addressed. The existing traceback scheme employed either packet marking or packet logging approaches. However, for successful traceback, these schemes need large number of attack packets. To overcome this drawback Al-Duwairi and Manimaran presented hybrid traceback schemes which combine both approaches. The schemes include Distributed Link- List Traceback (DLLT) and Probabilistic Pipelined Packet Marking (PPPM). In this paper we implement the hybrid traceback schemes presented by them using a prototype application which demonstrates the proof of concept. The empirical results revealed that the proposed system traces back the source of attack effectively.

Abstract: Information is increasingly important in our daily life. Information gets more value when shared with others. Due to advances in technologies related to networking and communication, it is possible to share the information like audio, video and image easily. It may give rise to security related issues. Attackers may try to access unauthorized data and misuse it. To solve this problem certain techniques are required. Techniques to provide security, while sharing information are termed as Secret sharing schemes. When it comes to visual information like image and video, it is termed as Visual secret sharing scheme. Visual cryptography (VC) is a technique used for protecting image-based secrets. The basic concept of visual cryptography scheme is, to split secret image into some shares, which separately reveals no knowledge about the secret information. Shares are then distributed to participants. By stacking these shares directly, secret information can be revealed and visually recognized. All shares are necessary to combine to reveal the secret image. Starting from the basic model, many visual cryptographic techniques have been evolved day by day.

Abstract: The Human-Computer Interaction (HCI) is a field in which the developer makes a user friendly system. In this paper, a real-time Human-Computer Interaction based on the hand data glove gesture recognition is proposed. This paper presents a wearable prototype model for Hand gesture recognition system using MEMS which is capable of recognizing eight hand gesture, based on the signal from 3-axes MEMS accelerometer. The accelerations of a hand motion in three perpendicular directions are detected by accelerometers and acceleration values were transmitted to microcontroller. An automatic gesture recognition algorithm is developed to identify individual gestures in a sequence. Finally, the gesture is recognized by comparing the acceleration values with the stored templates. According to recognized gestures, respective commands are performed. HCI is becoming more and more natural and intuitive to be used. The important part of body that is hand is most frequently used as interaction in digital environment and thus complexity and flexibility of motion of hand is a research topic[5]. The gestures classified are clicking, dragging, rotating, pointing and ideal position. Recognizing these gestures relevant actions are taken, such as air writing and 3D sketching by tracking the path. The results show that glove used for interaction is better than normal static keyboard and mouse as the interaction process is more accurate and natural. Also it enhances the user's interaction and immersion feeling by eye blink sensor.

Abstract: Data mining is extensively studied field of research area, where most of the work is highlighted over knowledge discovery. Data stream is dynamic research area of data mining. A data stream is an enormous sequence of data elements continuously generated at a fast rate. In data streams, huge amount of data continuously inserted and queried, such data has very large database. The data stream is motivated by emerging applications involving massive data sets for example, consumer click streams and telephone records, bulky sets of web pages, multimedia datas, and financial transactions and so on. It raises new problems for the data stream community in terms of how to mine continuous arrival of high speed data items. Recently many researchers have focused on mining data streams and they proposed many techniques for data stream classification, data stream clustering and finding frequent items from data streams. Data stream clustering techniques are highly helpful to cluster the similar data items in data streams and also to detect the outliers, so they are called cluster based outlier detection. This main objective of this research work is to perform the clustering process in data streams and detecting the outliers in data streams. In this research work, two clustering algorithms namely BIRCH with K-Means and Birch with CLARANS are used for clustering the data items and finding the outliers in data streams. Different types, sizes of data sets and two performance factors such as clustering accuracy and outlier detection accuracy are used for analysis. By analysing the experimental results, it is observed that the proposed BIRCH with CLARANS clustering algorithm performance is more accurate than the existing algorithm BIRCH with K-Means.

Abstract: Audio mining or audio indexing is a speech recognition technique that is used to search audio signals for occurrences of spoken words or phrases. Speech technology is used to recognize the words or phonemes that are spoken in an audio or video file and audio mining searches can then be carried out to locate specific words and phrases within the audio. These audio mining searches run at speeds that are typically many thousands of times faster than real time, so large quantities of audio or speech can be searched in a short time. This paper poses a light on various audio mining techniques like LVCSR audio mining and Phonetic audio mining along with their comparison. With the voluminous increase in the amount of audio content on the internet and other sources, it is clear that audio mining is a growing technology. Audio mining has been used for searching television captions and other media content because the audio mining search is able to locate the speech content associated with the text for each caption. The purpose of this paper is to provide a systematic overview of audio mining.

Abstract: Machine learning approach has got major importance when distribution of data is unknown. Classification of data from the data set causes some problem when distribution of data is unknown. Characterization of raw data relates to whether the data can take on only discrete values or whether the data is continuous. In real world application data drawn from non-stationary distribution, causes the problem of "concept drift" or "non-stationary learning". Drifting of dataset is often associated with online learning scenario. The goal of intelligent machine learning algorithms is to be able to address a wide spectrum of real world scenarios, then the need for a general framework for learning from, and adapting to, a non- stationary environment that may introduce imbalanced data can be hardly overstated. This paper focus on imbalanced data that results in unequal representation of classes in a pattern recognition problem. There are typically two types on class in an imbalanced pattern recognition problem, majority (negative) and minority (positive).

Abstract: Gene Ontology is structured as a directed acyclic graph, and each expression has distinct interaction to one or more other terms in the same domain and sometimes to other domains. High throughput techniques have become a primary approach to gathering biological data. These data can be used to explore relationships between genes and to identify disease. Clustering is a common methodology for the analysis of array data and many research laboratories are generating array data with repeated measurement. Cluster analysis seeks to division a given dataset into groups based on specified features so that the data points within a group are more similar to each other than the points in different groups. The gene ontology is a gene(gene products)using terms from three structured vocabularies: Biological process, cellular component and molecular function. For measuring the semantic similarity on GO terms using novel method, namely shortest path (SP) algorithm.

Abstract: Feature selection has been an active research area in pattern recognition, statistics and data mining community. Idea behind feature selection is to choose a subset of input variables by eliminating features with little or no predictive information. Feature selection (FS) is to determine a minimal feature subset from a problem domain while retaining a suitably high accuracy in representing the original features. This can significantly improve the comprehensibility of the resulting classifier models and often build a model that generalizes better to unseen points. Rough set theory (RST) can be used as a tool to discover data dependencies and to reduce the number of attributes contained in a dataset using the data alone, requiring no additional information. In this paper, feature selection technique has been used in high dimensional data for removing irrelevant features and producing high accuracy for post processing data.

Abstract: Question and Answer (Q&A) system based on social network gains more attention recently. The social-based Q&A systems answer non-factual questions, which cannot be easily resolved by web search engines. These systems either rely on a centralized server for identifying friends based on social information or broadcast a user's questions to all of its friends. Mobile Q&A systems, where mobile nodes access the Q&A systems through internet, are very promising considering the rapid increase of mobile users and the convenience of practical use. However, such systems cannot directly use the previous centralized methods or broadcasting methods, which generate high cost of mobile internet access, node overload, and high server bandwidth cost with the tremendous number of mobile users. We propose a distributed social- based mobile Q&A system with low overhead and system cost as well as quick response to question askers. It enables mobile users to forward questions to potential answerers in their friend lists in a decentralized manner for a number of hops before restoring to the server. It leverages lightweight knowledge engineering techniques to accurately identify friends who are able to and willing to answer questions, thus reducing the search and computation costs of mobile nodes. The trace- driven simulation results show that Q&A system can achieve a high query precision and recall rate, a short response latency and low overhead.

Abstract: Wireless sensor networks have recently attracted significant attention for many military and civil applications, such as target tracking, surveillance and security management. Wireless sensors nodes have limited energy resources and are usually deployed in environments where recharging or replacement of the battery is either impossible or too costly. Therefore, energy resources for wireless sensor networks should be managed wisely to extend the lifetime of networks. There are several number of energy efficient protocols which have been used to prolong the network lifetime of the wireless sensor networks. These protocols can further be improved to achieve better results. In this paper, "an energy efficient three level hierarchical clustering protocol" for wireless sensor networks is proposed. The fundamental concept of this protocol is that there is a pre-defined radius around the Base Station (located at centre), some nodes are inside the radius and others are outside the radius. Cluster Heads which are outside the radius find the nearest Cluster Head which is inside the radius and send data to it. Then these inside Cluster Heads aggregate the data and send it to the Base Station. The proposed scheme is compared against LEACH protocol. Simulations have been conducted to evaluate these protocols and favorable results are obtained. Our results show that TLHCLP improves network lifetime by an order of magnitude compared with LEACH.

Abstract: Communication process in mobile ad hoc network is based on multihopping system for routing to create a path between source and destination. If we found a solid and sound path for routing the packets that would be more reliable, adaptable and efficient for the various network scenarios too by following the next hop method and that also should be the farthest node within the cluster, then we could get superior work by the networks. This paper provides stress on same fact by means of simulating the protocol e-EPSAR over ADOV (reactive) existing protocol. In addition this research paper also shows the few simulations of e- EPSAR over multiple network (i.e. expands in the form of number of nodes) and evaluate the performance and feasibility of e- EPSAR by taking into account the various parameters of network such as Packet Sent, Packet Received, Ratio of Packet Delivery and End-to-End Average Delay. The simulations have been performed using Network Simulator 2 version 2.35. The performance obtained is better than available EPSAR.

Abstract: In multi-instance learning, the training set comprises labeled bags that are composed of unlabeled instances, and the task is to predict the labels of unseen bags. Multiple-instance learning is a variation on supervised learning, where the task is to learn a concept given positive and negative bags of instances. Each bag may contain many instances, but a bag is labelled positive even if only one of the instances in it falls within the concept. A bag is labelled negative only if all the instances in it are negative. This paper discusses the multi-instance problem using two-level distribution (TLD) algorithm.

Abstract: In today's scenario content sniffing and cross-site scripting (XSS) vulnerabilities are the major security threats today when we are in the server-client environment or using any web browser. Contents sniffers alter the content or the source code of the web pages used in their attacks to mimic changes to legitimate websites. So the content transmission and receiving in several forms are not transaction safe. In this paper we put our significant study in the direction of content sniffing and want to find the better security prevention mechanism and discuss on attack detection strategy, so that the attack alert should be sent in a specific time duration.

Abstract: VANETs is a technology that provides communication between moving vehicles. VANETs are a type of Mobile Ad-Hoc networks in which moving vehicles will act as nodes. VANETs are highly dynamic in nature due to mobility of nodes and this dynamic nature causes topological change in the network, which may affect the communication and security of whole network. There are various attacks which may effect the network but wormhole attack is one the harmful attack which may affect the communication in VANET. This is so because wormhole may lead to attacks like Denial of service attack, data tampering, masquerading etc. In this paper performance of different routing protocols are analysed on the basis of metrics like throughput, end-to-end delay and jitter. Performance of routing protocols are analysed in two cases first is without wormhole attack and second is with wormhole attack and it has been checked how much performance of routing protocols AODV, OLSR and ZRP are degraded with wormhole attack.

Abstract: Grid computing is an emerging technology in distributed systems that provide a high performance computing platform to solve larger scale applications by coordinating and sharing computational power, data storage and network resources. All Grid resources are heterogeneous. A grid integrates and coordinates resources and users of different administrative domains inside the same company or in different countries. Task scheduling is one of the key research areas in grid computing. Scheduling is the NP Complete problem which allocates resources for the incoming tasks to the resource broker. Scheduling problem may become tedious when the resources are dynamic and the size of Grid in increased. The goal of scheduling is to achieve highest possible system throughput and to match the application's need with the available computing resources. This paper primarily focuses on scheduling the tasks to the available resources in the Grid environment. The resource allocation process is based on Artificial Bee Colony (ABC) algorithm. The objective of this algorithm is to generate optimal solution dynamically. By this scheduling, the task is completed in minimum time and uses the available resources in efficient manner. In proposed method Single Shift Neighborhood (SSN), Double Shift Neighborhood (DSN), Ejection Chain Neighborhood (ECN) and Genetic Algorithm (GA) techniques are applied for migration of jobs to the resources and the result are compared based on makespan and resource utilization. The result shows that Genetic Algorithm technique will give better results when compared to Single Shift and Double Shift Neighborhoods. This heuristic algorithm provides an optimal task scheduling in all heterogeneous computing environments.

Abstract: Lung cancer is one of the most dangerous cancer's type in the world. Early detection can save the life and survivability of the patients. In this paper we want to propose a solution in the direction of lung cancer symptom detection. In this paper we proposed a new algorithm that is support based ant colony optimization technique (SPACO). Our algorithm is broadly divided into three parts, in the first part we accept the data set of cancer symptoms which is a generalized way for creating the patterns for Lung Cancer Framework, and in the second part we find the relevant data from the patterns. We can choose the frequent symptoms only by using the support count value. According to the support value we decide the ants and pheromone value. We initialize the pheromone value which is the support of the pattern of cancer symptoms. It is updated in each trial. By updating the pheromone value in each step we can check the symptom quality which either increases the prediction or decreases the prediction. Finally by result analysis we can prove the effectiveness of our algorithm.

Abstract: In wireless communication networks Ad-hoc networks are plays dominant role, Mobile Ad-hoc network (MANET) is a collection of wireless mobile nodes that dynamically form a network temporarily without any central administration. The primary objective of this research work is to study and investigate the performance of Dynamic source routing (DSR) protocol and Energy efficient routing protocols like MBCR and MMBCR. Energy efficient routing is one of the important design criterions for MANET since mobile nodes are battery powered with limited capacity and which cannot be recharged whenever needed. So the MANET routing is challenged by power and bandwidth constraints. We use CBR based Traffic models to analyses the performance of routing protocols based on parameters of Packet Delivery Ratio, Average end to end Delay, Energy Consumption, Node Analysis, Network Lifetime and through put. We have used NS-2 Simulator for simulation.

Abstract: Graphical passwords provide a promising alternative to traditional alphanumeric passwords due to the fact that humans can remember pictures better than text. A simple graphical authentication system that consists of a sequence of ânâ images and the user has to select the click points associated with one of the ânâ image for login. The proposed mechanism is a more secure graphical password authentication which consists of a sequence of ânâ images in the grid format and the user is asked to select a precise image from the grid during registration. This authentication system employs the userâs personal handheld device or E-mail as the second factor of authentication. In the login phase, the user enters the username to the website. The username transmitted to the database by the server and it displays a set of images in grid. A precise image is selected from the "n" images and is provided to the server. The server generates a random pixel value from the selected picture and sends it to handheld device. The user is asked to do five click points on the image according to the pixel value in some specific order within some time constraints (e.g. if there are 10 random pixel value user should enter [2], [4], [6], [8], [9] pixel value for successful login); the pixel value acts as a onetime password. The user is authenticated only if he/she selects and clicks on the correct pixel value. The inaccurate pointing of pixel value leads to the unsuccessful authentication and the login access get denied.

Abstract: The explosion of social media has created unprecedented opportunities for citizens to publicly voice their opinions, but when it comes to making sense of these opinions then it is a serious problem. Opinion mining is a type of natural language processing for tracking the mood of the public about a particular product. Opinion mining involves building a system to collect and examine opinions about the product made in blog posts, comments, reviews or tweets. Opinion mining can be useful in several ways in marketing, it helps to judge the success of a launch of new product, determine which versions of a product or service are popular and even identify which demographics like or dislike particular features. After the process of opinion extraction, the Sentiment analysis determines the subjectivity, polarity and polarity strength of a piece of text. The sentiment oriented words are used for providing a good recommendation to the users to make accurate decision. This paper gives a brief survey on the opinion mining framework.

Abstract: A new system is proposed called TACS, trusted and attacker free credit based scheme for wireless networks. It is for stimulate node co-operation, avoid packet drop, and regulate packet transmission. The node submits report to the trusted party after the communication is over and store a temporarily undeniable token called evidences. The trusted party verifies the report and clears the payment of fair report with no processing overhead. For cheating reports evidences are requested to identify and remove cheating node from the system. In the new system all the attacker nodes are removed before beginning the communication and a trust value is assigned to all the nodes. This will improve the security of the system and it has low communication overhead, processing overhead.

Abstract: A compact, single feed, multi frequency design of reconfigurable microstrip antenna with various slots are presented in this paper. A rectangular patch loaded with horizontal slots having extended slot arms constitutes the fundamental structure of the antenna. The tuning of the multi resonant frequencies is realized by varying the effective electrical length of the slots by loading varactor diodes across the slots. A size reduction of 84% for the lower operating frequency is obtained when compared to conventional rectangular microstrip patch. Proposed antennas are useful for multi-band wireless applications like GSM1800, IMT2000, WLAN etc operating over a wide range of bands. Measured and simulated results of return loss, antenna gain and radiation patterns are also discussed.

Abstract: Resolvers are angular position transducers used to measure the absolute angle. These are mounted on the motor shaft to measure the shaft's absolute angular position. This paper discusses the design of software based Resolver to Digital Converter (RDC) using pulse excitation and is implemented in MATLABÂŽ SIMULINKÂŽ. In the proposed simulation model, inverse tangent algorithm is proposed to measure the motor shaft angle. The resolver rotor is excited with a pulse signal and the resolver two output signals are proportional to sine and cosine of the motor shaft angle. These modulated output signals are sampled by two Analog to Digital Converters (ADCs), with a sampling frequency equal to that of excitation frequency. The angle is measured by applying inverse tangent algorithm to the samples values of sine and cosine signals. The proposed software based RDC model is successfully implemented and the performance of the model is validated through various rotor speeds.

Abstract: Voice over IP (VoIP) is an emerging communication service allowing voice transmission over a private or a public IP network. VoIP allows significant benefits for customers and service providers including cost savings, phone and service portability, mobility, and the integration with other applications. Nevertheless, the deployment of the VoIP technology encounters many challenges such as interoperability issues, security issues, and QoS concerns. Among these disadvantages, QoS issues are considered the most serious due to the QoS problems that may arise on IP networks, and the stringent QoS requirements of voice traffic. The aim of this paper is carry out a deep analysis of the QoS concerns of the VoIP technology. Firstly, we present a brief overview about the VoIP technology. Then, we discuss the QoS issues related to the use of the IP networking technology for voice traffic transmission. After that, we present the QoS concerns related voice clarity. Finally, we present the QoS mechanisms proposed to make the IP technology able to support voice traffic QoS requirements in terms of voice clarity, voice packet delay, packet delay variation, and packet loss.

Abstract: Electrocardiogram (ECG) signal play important role in diagnosis and survival analysis of heart diseases. Various techniques have been proposed over the years addressing the signal compression. Compression of ECG signals is desirable for three reasons- economic use of storage data, reduction of the data transmission rate and transmission bandwidth conversation. In this paper a comparative study of Discrete Fourier Transform (DFT), Fast Fourier Transform (FFT), Discrete Cosine compression and Discrete Wavelet Transform (DWT) is used. Different ECG signals taken from MIT-BIH arrhythmia database are tested. The experimental results are obtained for Percent Root Mean Square Difference (PRD) and Compression ratio (CR). The result of ECG signal compression shows better compression performance for DCT and DWT with appropriate PRD. The main purpose of this research work is to compare the major techniques of ECG signal compression in a single view.

Abstract: Data mining is the domain which has utility in real world applications. Data sets are prepared from regular transactional databases for the purpose of data mining. However, preparing datasets manually is time consuming and tedious in nature as it involves aggregations, sub queries and joins. Moreover the traditional SQL aggregations such as MAX, MIN etc. can generate single row output which is not useful in generating datasets. Therefore it is essential to build horizontal aggregations that can generate datasets in horizontal layout. These data sets can be used further for data mining in the real world applications. This paper focuses on building user-defined horizontal aggregations such as PIVOT, SPJ and CASE whose underlying logic uses SQL queries. We built a prototype that demonstrates the efficiency of the proposed horizontal aggregations. The empirical results revealed that the prototype is effective and can be used in real world applications.

Abstract: A radar waveform generator is implemented and it is designed by using directly digital modulation method based on DDS. It is able to generate arbitrary signals whose frequency amplitude and phases are controlled by the description words which will be given from external computer. Accurate waveforms are generated. By using Direct digital synthesis technique we can generate waveforms digitally . DDS technique is widely applicable and simple. Direct Digital Synthesizer (DDS) is a frequency synthesizer and it can generate arbitrary waveforms by using single, fixed- frequency reference clock. Some of the DDS Applications are: function generators, modulators. For implementing radar waveform generator along with DDS we need FPGA and PIC microcontroller. To generate the waveform using DDS we need to store the hexadecimal data into the internal registers of DDS chip along with that we need some control signals which will be generated using FPGA . First in PC we need to enter the information of the signal to be generated for that we need design a Graphical User Interface (GUI).In GUI we will enter the amplitude, frequency and phase of the waveform to be generated and then it has to covert that particular data into hexadecimal data based on the formulas mentioned in AD9910 datasheet, then it has to send that data to microcontroller through serial port. Now, microcontroller will receive that data from PC and then it has to send that data to the FPGA. FPGA will receive that data, along with that it has to generate some control signals and clock signals based on the control signals, received data has to be send to the internal registers of DDS chip.

Abstract: Data Stream mining is a process of extracting knowledge structure from continuous and rapid data records. Data stream size is extremely large. It's a continuous flow of data So major problem related to data stream is infinite length, concept evolution and concept drift. Novel class detection is very interesting topic in a data stream mining. We can detect novel class using classification and clustering. Currently mostly uses decision tree using classification. In that Hoeffding Tree is better for data stream mining. And Hoeffding Option Tree is more better than Hoeffding Tree. In our paper we can use new voting method which is different than HOTDC. In our method we can use classification . So its supervised learning. Here classes are fixed before examined data. But when continuous data come then not all data are classified. Some data are misclassified. And this class is not in universal existing class then its known is a novel class. In our method when this type of class is detected then model is trained. So no require to collect those type of data. So when again this type of instance is come then its classified in that class. Using that method we can release from problem concept drift, concept evolution and infinite length.

K. SRIDEVI, DR. R. UMARANI Assistant Professor, Department of Computer Science, Nehru Memorial College, Puthanampatti, Trichy District, Tamilnadu, India Associate Professor, Department of Computer Science, Sri Sarada College for Women, Salem, Tamilnadu, India
Abstract: Semantic Web is the representation of knowledge which consists of a huge amount of ontologies. Ontologies provide an efficient way to reduce the amount of information overload by defining the structure of a specific domain and enabling easier access to the information. Since the demand for the use of ontology has been increased, similar to the Web searching, ontologies on the Semantic Web are to be searched in an efficient way. Ontology search can prove its excellence only when the retrieval involves with highly relevant information based on the user query. The ranking method increases the scope of the knowledge searching and makes the users to view the relevant need for the query on the top most. There are a number of Semantic search engines available to aid in the discovery and ranking of ontologies, but with benefits and pitfalls. This paper reviews most of the ontology ranking methods used, which will help the researchers to proceed further.

Customized SQL Aggregations for Generating Data Sets
SUNEETHA.M, KIRAN KUMAR.G Student, Department of CSE, MLRIT, Hyderabad, India HOD, Department of CSE, MLRIT, Hyderabad, India
Abstract: Data mining is the domain which has utility in real world applications. Data sets are prepared from regular transactional databases for the purpose of data mining. However, preparing datasets manually is time consuming and tedious in nature as it involves aggregations, sub queries and joins. Moreover the traditional SQL aggregations such as MAX, MIN etc. can generate single row output which is not useful in generating datasets. Therefore it is essential to build horizontal aggregations that can generate datasets in horizontal layout. These data sets can be used further for data mining in the real world applications. This paper focuses on building user-defined horizontal aggregations such as PIVOT, SPJ and CASE whose underlying logic uses SQL queries. We built a prototype that demonstrates the efficiency of the proposed horizontal aggregations. The empirical results revealed that the prototype is effective and can be used in real world applications.

Abstract: This paper discusses a variety of obfuscation techniques used by metamorphic malware to change the structure of new variant. Mutation engine is associated with each metamorphic malware which is responsible to make the changes in the structure of new variant using variety of obfuscation techniques. In most of the metamorphic malware, the size of mutation engine remains a little bit small in order to bypass detection. The main objective of malware writers is to make code as complicate as possible along with modern obfuscation techniques. As per our survey, there is not an efficient algorithm to deal with these metamorphic codes. The conventional signature based algorithm used by most of antivirus software is even failed against the metamorphic families.

A Novel Anti Phishing Framework Based On Visual Cryptography
MOUNIKA REDDY.M, MADHURA VANI.B Student, Department of CSE, MLRIT, Hyderabad, India Asst.Professor, Department of CSE, MLRIT, Hyderabad, India
Abstract: Phishing is one of the attacks that became popular recently. It is an identity theft attempt in order to obtain confidential and private information of individuals or companies for monetary or other gains. In the recent part there were many reports on phishing attack in many financial domains including banking. It has become a serious threat to enterprises that deal with financial transactions. If these threats are not addressed thoroughly, people can't trust online transactions that involve due authentication through credentials. Many solutions came to solve this kind of identity theft. Recently James and Philip proposed a new approach based on visual cryptography to address the issue of phishing. This will automatically preserve the privacy of captcha. It achieves this by dividing the original image into two shares which are to be stored in different databases. The decryption is possible only when adversaries can provide both shared at a time. The individual shares can't reveal the original captcha. In this paper, we implement the visual cryptography using C# programming language for building an anti-phishing framework. The experimental results revealed that the proposed application is secure and can prevent phishing attacks.

Abstract: Cloud computing has changed the way computing takes place significantly. It is a new computing model which enables parties to make use of its services such as Infrastructure as a Service (IaaS), Software as a Service (SaaS) and Platform as a Service (PaaS) in pay per use fashion. The users of cloud computing need not to indulge in huge capital investments as the resources are made available by cloud service providers. There are security challenges in cloud computing. One such challenge is data theft attacks. The existing mechanisms such as encryption are not able to present insider data theft attacks. Recently Stolfo et al. presented a mechanism to prevent insider data theft attacks using offensive decoy technology. In this paper we implement this technology by building a web based prototype that demonstrates the efficiency of the decoy technology. When the application suspects unauthorized access it throws challenges besides launching disinformation attack using decoy information. This prevents insider theft. The empirical results revealed that the mechanism is capable of providing security against insider data theft attacks.

Abstract: Satellite imageries are categorized as both panchromatic and multispectral images. The panchromatic image has higher spatial resolution while the multispectral image has relatively lower spatial resolution but are rich in spectral information .The fusion of these two can produce a better imagery . Most of the fusion methods available to merge a high- resolution panchromatic image and low-resolution multi-spectral images may distort the spectral characteristics of the multi-spectral image or the spatial resolution of he panchromatic image may reduce. In this paper, a fusion algorithm for multi-spectral and panchromatic images based on spatial weightage called region correlation coefficient and in the Nonsubsampled Contourlet Transform (NSCT) Domain is proposed. The proposed fusion idea partitions both the source images into regions and Region Correlation Coefficient (RCC) is calculated between the corresponding regions of multispectral and panchromatic images .This RCC determines the regions of multispectral image with better spatial resolution and those with better spectral quality. The fusion is performed in NSCT domain. For that NSCT is performed on individual regions of panchromatic image and intensity component of multispectral image at different scales and directions. The obtained NSCT coefficients are fused taking into consideration the spatial weightage factor. Performance analysis show that the algorithm proposed is better than the IHS transform method and simple NSCT method.

Abstract: Multiple-path source routing protocols allow a data source node to distribute the total traffic among available paths .This paper proposes technique for the network nodes to estimate and characterize the impact of jamming and for a source node to incorporate these estimates into its traffic allocation. And we have shown that in multi-source networks, this centralized optimization problem can be solved using a distributed algorithm based on decomposition in network utility maximization. We formulate this traffic allocation as a lossy network flow optimization problem using portfolio selection theory from financial statistics which allow individual network nodes to locally characterize the jamming impact and aggregate this information for the source nodes. We demonstrate that the use of portfolio selection theory allows the data sources to balance the expected data throughput with the uncertainty in achievable traffic rates.

Abstract: Cloud computing has been conceived of tangible solution to the uprising storage economy of IT enterprises. Cloud computing is the long dreamed vision of computing as a utility, where users can remotely store their data into the cloud so as to enjoy the on-demand high quality applications and services from a shared pool of configurable computing resources. By data outsourcing, users can be relieved from the burden of local data storage and maintenance. However, the fact that users no longer have physical possession of the possibly large size of outsourced data makes the data integrity protection in Cloud Computing a very challenging and potentially formidable task, especially for users with constrained computing resources and capabilities. In this paper we propose a technique based on Metadata of the files, by using this metadata, we can verify the data that is stored by a user at remote storage in the cloud is not modified by the archive and Third party verifier. To perform cryptographic operations (encryption and decryption) required lot of computing power, but computation power is different for Personal computers, laptops and handheld devices, with this technique there may be a chance to reduce the number of cryptographic operations.

Abstract: The vast potential of wireless sensor networks (WSN) is an emerging area of research in recent years. WSN consists of spatially distributed autonomous sensors to monitor the physical or environmental conditions like temperature, sound, pressure and to cooperatively pass their data through the network to the main location. The advantage of wireless sensor network is that they can be used with ease in the environment where wired system cannot be used or if used, are to be treated with caution. The WSN is built of nodes, may vary from few to several thousands. Each sensor node has typically several parts- radio transceiver with internal or external antenna, a microcontroller for interfacing with the sensors, energy source or battery. Zigbee is one of the latest and upcoming technologies in the field of WSN. In this paper we present the multipoint temperature monitoring using embedded PSoC microcontroller and Zigbee technology through a wireless data logger and display the temperature on the PC's screen.

Abstract: Cloud storage has become an attractive and cost effective alternative for enterprises to outsource their valuable business data. However, there are security concerns pertaining to the integrity of data as the cloud server is treated as "untrusted". To overcome this problem many security schemes came into existence. Recently Zhu et al. presented a technique known as Provable Data Possession (PDP) for data integrity in cloud with distributed storage mechanisms. They considered multiple cloud service providers to store data in cooperative fashion. Their solution makes use of homomorphic verifiable response indeed and multi-prover zero-knowledge system for ensuring data integrity. In this paper we practically implement the PDP scheme proposed by Zhu et al. and build a prototype application to demonstrate the proof of concept. The empirical results reveal that the PDP scheme is very effective and can be used in real time multi-cloud environments.

Abstract: Steganographic techniques have been used for ages and they date back to ancient Greece. The aim of steganographic communication back then and now, in modern applications, is the same: to hide secret data (a steganogram) in an innocently looking cover and send it to the proper recipient who is aware of the information hiding procedure. In an ideal situation the existence of hidden communication cannot be detected by third parties. What distinguishes historical steganographic methods from the modern ones is, in fact, only the form of the cover (carrier) for secret data. Historical methods relied on physical steganography - the employed media were: human skin, game, etc. Further advances in hiding communication based on the use of more complex covers, e.g. with the aid of ordinary objects, whose orientation was assigned meaning. This is how steganograms were introduced. The popularization of the written word and the increasing literacy among people had brought about methods which utilized text as carrier. Here we are giving the overview of network steganography history, evolution, principles, concepts and detection. The World Wars had accelerated the development of steganography by introducing a new carrier - the electromagnetic waves. Presently, the most popular carriers include digital images, audio and video files and communication protocols. The latter may apply to network protocols as well as any other communication protocol (e.g. cryptographic).The way that people communicate evolved over ages and so did steganographic methods. At the same time, the general principles remained unchanged.

A Novel Replica Allocation Approach Depth-First Iterative-Deepening for Handling Selfishness in MANETs
D. FRANCIS XAVIER CHRISTOPHER, C. AMIRTHAM Director, School of Computer Studies, RVS College of Arts and Science, Coimbatore, India Research Scholar, Department of Computer Science, RVS college of Arts and Science, Coimbatore, India
Abstract: In mobile unexpected networks (MANET), nodes move freely and therefore the distribution of access requests changes dynamically. Duplicate allocation in such a dynamic atmosphere may be a important challenge. The communication price has become an outstanding issue influencing the performance of duplicate allocation within the MANET environment. In reality, however, some nodes might egotistically decide solely to work part, or not in the least, with alternative nodes. These selfish nodes may then scale back the knowledge accessibility within the network. In this paper, the impact of selfish nodes in a very mobile unexpected network from the angle of duplicate allocation is examined. This can be termed as selfish duplicate allocation. Especially, a selfish node detection formula is developed during this research work that considers partial selfishness and novel replica allocation technique to properly deal with selfish replica allocation. Depth-First Iterative-Deepening formula is used during this in this work for higher performance.

Abstract: Cloud computing is based on the concepts of distributed computing, grid computing, utility computing and virtualization. It is a virtual pool of resources which are provided to users via Internet. Cloud computing service providers one of the goals is to use the resources efficiently and gain maximum profit. This leads to job scheduling as a core and challenging issue in cloud computing. In this research a discussion towards the resource management of virtual machines in cloud and how to make resources more efficiently available to clients is provided. The main focus is on job scheduling. In this present work, a parametric analysis is performed to identify the requirement of process migration and based on this analysis the migration will be performed on these processes. . The effectiveness of the work is identified in terms of successful execution of the processes within the time limits. A comparative study is also done using Matlab.
Keywords: Virtual machines, Matlab, Scheduling, and Migration.

Abstract: This paper presents design, modeling and simulated characterization of proximity coupled fed circular microstrip patch antenna (PCMPA) where the electromagnetic radiating patch is totally composed of nano thickness (nano meter) film. The nano film is excited through an electromagnetic coupling scheme also known as proximity coupler at 10 GHz. Antenna design and parametric studies have been executed through IE3D version 14.65 simulation software. Simulation result shows enhanced bandwidth and good return loss response of nano film patch antenna over traditional bulk thickness (micro meter) patch antenna. Since, the resonance frequency of this antenna is around 10 GHz; these antennas are suitable for X- band applications such as satellite communication, radar, medical, and other wireless systems.

Abstract: The existing security mechanisms of Wireless Sensor Networks (WSNs) authenticate communication between sensor nodes and mobile sinks. However key predistribution is a problem. Moreover the usage of mobile sinks for data collection also throws new security challenges. When one or more nodes are compromised, an attacker can collect large number of security keys. With the keys stolen an attacker can replicate a mobile sink and collect sensitive data illegally. Many schemes came into existence for secure communications in WSN. However, three - tier security scheme proposed by Rasheed and Mahapatra uses two key pools. One pool is for mobile sink and the other pool for pair wise key establishment between sensors. It also has mechanisms between access node and sensor node to avoid node replication attacks. In this paper we implemented this three tier security scheme. NS2 simulations revealed that the security framework is robust to node and sink replication attacks.

Analysis of MD5 Algorithm Safety against Hardware Implementation of Brute Force Attack
AL-MARAKEBY Systems and Computers Engineering Dept., Faculty of Engineering, Al-Azhar University, Cairo, Egypt
Abstract: MD5 is one of the most widely used hash functions generating 128 bits cipher. Theoretically, this algorithm requires 2128 iteration for brute force attack. This complexity represents a challenge on cracking this algorithm due to the computational time. The hardware implementation of algorithm cracking increases the speed dramatically. In addition to that, using MD5 for the encryption of weak and short passwords reduces the iterations and allow breaking the password in few seconds or minutes. In this paper, the MD5 algorithm resistivity and safety has been analysed based on FPGA implementations. Different parallel architectures for implementing the algorithm have been investigated. Different sets of strong and weak passwords have been used to test these architectures. The time for cracking the cipher has been measured indicating the performance of the MD5 algorithm.
