Energy-Efficient Clusterhead Selection Scheme in Heterogeneous Wireless Sensor Network

Abstract

The applications of wireless sensor network (WSN) are growing very rapidly, so utilizing the energy in an efficient manner is a challenging task as the battery life of nodes in WSN is very limited. For enhancing the lifetime of the network, various clustering protocols have been proposed earlier. In this paper, a clustering protocol named Energy Efficient Clusterhead Selection Scheme (ECSS) is proposed. The proposed ECSS protocol focusses on selecting an energy-efficient cluster head (CH), which helps in enhancing the overall lifetime and performance of the network. The proposed ECSS protocol uses the energy levels of nodes for the CH selection process. The proposed protocol is designed for the heterogeneous environment and it aims in minimizing the energy usage in the network and thereby improving the lifespan of the network. To measure the performance of the proposed ECSS protocol, the comparison is performed with the various existing protocols using MATLAB simulator. The results of simulation show that the proposed ECSS protocol has enhanced the network lifespan, throughput, and energy usage of the network as contrasted to the existing protocols.
