Performance Analysis of New Hybrid Distributed Energy Efficient Clustering Approach for WSNs

Abstract

One of the biggest obstacles to the development of wireless sensor network (WSN) is achieving energy efficiency. Since transmission accounts for the majority of energy consumption, clustering of the network is adopted by the research community to address this issue. In clustering protocols, the prime focus is given on cluster head selection method to achieve better network lifetime. In this paper, the cluster head selection is optimized by using Firefly method where the attractiveness of the nodes is computed using Firefly which optimizes the head selection process. The protocol was simulated in MATLAB and the performance of the network was analyzed based on energy consumed in the network and number of nodes alive. The proposed protocol showed better performance than the other two indicating the achievement of better network lifetime.
