Progress in wireless communication has made possible the development of low cost wireless sensor networks. Wireless sensor networks (WSNs) with a large number of small sensor nodes can be used for monitoring and controlling the physical environment from remote location with better exactness. This network due to the shared wireless communication medium and deployed unpleasant surroundings is fault prone. This paper introduces the new fault tolerant protocol to reduce overall power consumption, maximize the network lifetime in a wireless sensor network. Proposed FTEAP protocol, aims to decrease the consumption of the network resources in each round of data communication and aggregation and it is a fault tolerant technique that guarantees trustworthy of the communications between sensor nodes and base station by selecting strongest node as cluster-head and electing a reserved cluster-head. Simulation results demonstrate that the proposed algorithm has higher efficiency and can achieve better network lifetime and energy consumption.
