A Fault Tolerant Protocol for Wireless Sensor Networks

Today wireless sensor networks (WSNs) emerge as a revolution in all aspects of our life. WSNs have special specifications of themselves that made them different from other networks. Fault tolerance is one of the most significant of many challenges in these networks. In this paper, we present a cluster-based fault tolerant protocol that utilizes from energy efficient technique for clustering. We propose a novel mechanism for error detection. Our scheme detects faults and errors very accurately. Also, we propose a novel fault recovery technique to recover cluster-heads efficiently. Yet our scheme is accurate, saves energy of nodes too. That is very important for such networks.
