An Exploration on Existing Methods for Data Aggregation in Wireless Sensor Network

Abstract: WSN is the field where most challenging task is a lifetime of nodes with the support of data aggregation and can increase the lifetime of the network. In some utility comparable to wireless sensor community, knowledge mining, cloud computing data aggregation is the technology which is mostly used. In diverse sensor applications, the data has been gathered from the different individual nodes and aggregating at a base station. For reducing the consumption of energy, various networks execute in network aggregation of data at the neighbouring nodes and route to the base station. The main challenge is to secure aggregated data from disclosing during an aggregating process as well as to obtain accurate aggregated results.
