Design and Analysis of an Efficient Approach of Cluster Head Selection for Balanced Energy Consumption in Wireless Sensor Networks

Abstract

Since wireless sensor networks(WSNs) consist of massive tiny sensors for monitoring environmental data cooperatively and the energy resource of these nodes is nonreplenishable, protocols should concentrate on communication and processing technologies with the minimum energy cost. To improve energy efficiency and maximize the network lifetime, some cluster-based routing protocols are presented. In those protocols, cluster heads selection could be regard as an important issue and it will affect the lifetime of the whole network. In this paper, we propose an efficient approach of cluster head selection for balanced energy consumption in WSNs based on sensor nodes’ energy level and distance to the sink. Simulation results demonstrate our method can enlarge the life-time and balance the energy consumption well among all sensors.
