Performance Evaluation of Energy Efficient Protocols in Wireless Sensor Networks

Reducing the energy utilization is an important element in the Wireless Sensor network (WSN). Many protocols have been designed for improving energy efficiency of the network. Clustering protocols have been proved to be one of the energy-efficient protocols in WSN. One of the basic and most popular protocols designed using the clustering approach is the LEACH (Low-Energy Adaptive Clustering Hierarchy).However, LEACH undergoes an issue of bad distribution of cluster heads, which is overcome by implementing a technique of selecting smart cluster head in LEACH known as SCHS (Smart Cluster Head Selection).Also another clustering protocol HEED (Hybrid Energy Efficient Distributed) which follows the principle of LEACH is considered for the study purpose. In this paper, a thorough analysis of three clustering protocols was carried out by keeping the network parameters same so as to conclude which protocol amongst the three utilizes the minimum energy and prolongs the network lifetime
