Performance Analysis of Security Schemes in Wireless Sensor Network

Abstract: A Wireless Sensor Network (WSN) is a group of independent nodes, communicating wirelessly over limited frequency and bandwidth. The novelty of WSNs in comparison to traditional sensor networks is that they depend on dense deployment and coordination to execute their tasks successfully. Wireless Sensor Networks are used in many applications like military, ecological, and health-related areas. Security is the major concern in WSN due to its wireless communication nature and constraints like low computation capability, small memory, Bounded energy resources, susceptibility to physical capture, and the use of insecure wireless communication channels. These constraints make security a challenge to WSNs. The cryptographic schemes increases the security level and make it secure against different attacks. In this paper, different asymmetric and symmetric key cryptographic based security schemes like secure neighbour model, certificate model, ISAKMP (internet security association and key management protocol), IPSec (Internet protocol Security) and secure routing (ANODR i.e. anonymous on demand routing) are compared on WSNs. Providing security to sensor networks has a significant impact on QOS of sensor network. In this paper the QOS of WSN along with security schemes will be evaluated on the basis of metrics like throughput, end-to-end delay and energy consumption.
