Improvement in Cluster Head Selection Method by Considering Residual Energy and Distance between Nodes to Base Station in WSN

Abstract

Wireless Sensor Network(WSN) performs energy extensive tasks and it is essential to rotate the roll of cluster head to make it efficient. Hierarchical routing having cluster based topology is a very efficient approach for improving throughput. In this paper we aim to improve network life time by using LEACH based protocol by considering residual energy and distance of nodes in WSN. In our proposed approach we adopt dynamic clustering with dynamic selection of cluster heads in first round and static clustering with dynamic selection of cluster heads from second round. The protocol has been simulated in NS2 and results show improvement in energy efficiency, throughput, less packet drops and packet delivery ratio when compared to LEACH.
