Executive Summary

Routing protocols have been a challenging issue in wireless sensor networks. WSN is one of the focused are of research because of its multi-aspect applications. These networks are self-organized using clustering algorithms to conserve energy. LEACH (Low-Energy Adaptive Clustering Hierarchy) protocol is one of the significant protocols for routing in WSN. In LEACH, sensor nodes are organized in several small clusters where there are cluster heads in each cluster. These CHs gather data from their local clusters aggregate them & send them to the base station. On the LEACH many new schemes have been proposed to enhance its activity like its efficiency, security etc. In this paper the fault tolerance issue is being incorporated.
