Energy Consumption Analysis and Improvement Strategy for ClusterHead Rotation in Wireless Sensor Networks

Abstract

Abstract: To design a more energyefficient cluster head rotation (CHR) strategy for wireless sensor networks, this paper built an analytical model for the energy consumption of contentionbased CHR, analyzed the energy consumption ratio between data gathering and CHR, and proposed a schedulebased CHR, which could remove the energy consumption in CHR. The simulation results show that the schedulebased CHR obviously improves energy efficiency and energy consumption balance in the cluster.

Key words: wireless sensor networks, clustering, clusterhead rotation (CHR), energy efficiency
