Energy Consumption Balance Cluster-Head Selection Algorithm for Wireless Sensor Network

摘要

In this paper, we discuss the disadvantage of Low Energy Adaptive Clustering Hierarchy (LEACH) protocol. In LEACH● Cluster Head (CH)● is selected randomly without any parameter, such as node energy, distance. There exists a probability that energy consumption is unbalanced in WSN, which causes shortening its lifetime. In this paper, we proposed a new LEACH-based protocol, Dynamic Cluster LEACH (DCL). Firstly, all nodes are grouped based on location, and a CH is elected in every group, which ensures CHs even distribution in the network area. And an important factor selecting CHs, node energy is considered, which further energy consumption in WSNs. The results of simulation show that DCL● increase energy efficiency and prolong the network lifetime.
