Performance of an Energy Efficient Routing Scheme for Cluster-based Wireless Sensor Networks

Abstract

This paper proposes a novel energy efficient data clustering scheme to improve energy efficiency for cluster-based wireless sensor networks (WSNs). In order to reduce the energy dissipation of transmitting sensing data at each sensor, the fixed clustering algorithm uniformly divides the sensing area into clusters where the cluster head is deployed to the centered of the cluster area. Moreover, to perform energy efficient grid clustering (EEGC), the nodes take turns to be cluster head. Simulation results show that proposed EEGC definitely reduces the energy consumption of the sensors and prolongs network lifetime to be longer than LEACH for both life rate=50% and 70%. Moreover, the total transmission data of EEGC is more 60% than LEACH scheme.
