An Approach for Data Aggregation Strategy in Wireless Sensor Network using MAC Authentication

摘要

The WSN is currently in demand due to is bright application in both of the field of military and civil. However, for the wireless sensor network has limited energy and routing protocols are not suitable for traditional network. Data aggregation is an approach which supports lifetime of the wireless sensor networks (WSNs) against the limited energy. The proposed methodology deals with MAC authentication scheme for secure data aggregation that helps to achieve efficient secure data integrity and privacy with the improvement of energy efficiency and security. To avoid data loss in WSN, network is separated in different clusters, each cluster is headed by an aggregator (Cluster Head) and directly connected to sink through other CH. The methodology uses an algorithm for finding the cluster head on the basis of threshold value. The protocol uses a Homomorphic Encryption with secure hash Function algorithm for encryption and for calculating the hash value to maintain the integrity.
