Comparative Analysis of SEP, I-SEP, LEACH and PSO-Based Clustering Protocols in WSN

Abstract

Wireless sensor networks (WSNs) are significantly resource restrained by their bounded power supply. Hierarchical routing such as LEACH (Low-energy adaptive clustering hierarchy) is an effectual methodology, in which cluster has been structured; however, choosing an energy-sensible cluster by optimally selection of cluster heads (CH) is also very challenging. In present paper, extensive review and comparative study of hierarchical routing protocols such as stable election protocol (SEP), improved stable election protocol (I-SEP), and optimized versions of LEACH based on particle swarm optimization (PSO) are presented. Several parameters have been considered as the base of the study to reflect useful results in comparison of clustering protocol in WSN that leads to interesting findings in the form of results. The comparative study is examined over a variety of performances metrics such as alive nodes per round, packet to base station (BS) per round, and dead nodes per round. Based on the detailed consideration and observations, a qualitative conclusion is also drawn in the end.
