Energy efficient fault tolerant and clustering algorithm using alternative backup set for wireless sensor network

Abstract

In this paper, we proposed an efficient algorithm which works on two major issues fault tolerant and cluster formation. Clustering is an approach which helps to maintain the overall communications between the sensor nodes and cluster heads. This proposed algorithm also helps in recovery of cluster from sudden failure of cluster head at any round. An alternative cluster head (back up node) is deploying with all the clusters which activates when they received a HELP message from member sensor nodes whenever the member sensor nodes do not able to reach the cluster head.
