Cluster Head Selection Technique for Improving The Network Lifetime in WSN using ANP

Abstract

Improved network lifetime is an important criterion to evaluate the effectiveness of the Wireless Sensor Network. Clustering is one of the important methods for prolonging the network lifetime in Wireless Sensor Network (WSN). It involves grouping of sensor nodes into clusters and electing Cluster Heads (CHs) for all the clusters. CHs collect the data from respective cluster’s nodes and forward the aggregated data to base station. A major challenge in WSNs is to select appropriate cluster heads. In this paper, Authors present an Analytical Network Process (ANP) based Multi criteria decision making cluster head selection method. Five different criteria viz. Initial Energy (IE), Residual Energy (RE), Energy Consumption Rate (ECR), Average Energy of Network (AEN), Distance of nodes from CH (DNCH) have been used for selecting the cluster head from the available sensor nodes.
