Executive Summary

Wireless sensor networks are composed of low cost and extremely power constrained sensor nodes. In many applications of wireless sensor networks, a sensor node senses the environment to get data and delivers them to the sink via a single hop or multi-hop path. In wireless sensor networks, due to limited battery power of sensor nodes, one of the key challenge is to achieve minimum energy consumption in order to maximize network lifetime. Low Energy Adaptive Clustering Hierarchy (LEACH) is a well known routing protocol in WSN. It is a Clustering based protocol which helps in improving the lifetime of wireless sensor network This paper describes the comparative analysis of LEACH protocol with its various descendant protocols.
