Balanced Energy Efficient Grid Based Clustering Protocol for Wireless Sensor Network

Abstract

Due to the limited power of sensor nodes of Wireless Sensor Networks (WSN), routing in WSN becomes a hot topic for researchers to provide us several routing protocols for achieving minimum usage of power. Cluster size has a great effect on saving energy and enhancing the network lifetime in Cluster-Based Routing Protocols (CBRP). Energy consumption is increased either when the cluster is very large or very small. Therefore, optimum cluster size must be determined to enhance the Cluster-Based Routing Protocols performance. In this paper, authors will provide a mathematical analysis to calculate the optimum cluster size which is not clarified until now. On the basis of optimum cluster size, Balanced Energy Efficient Grid based Clustering protocol (BEEG) will be introduced. MATLAB will be used for evaluating the performance of our protocol. Simulation results show that proposed BEEG enhances the network lifetime and throughput more than other protocols such as LEACH, DCHS, K-LEACH, MOD-LEACH and Energy-LEACH.
