ABSTRACT
Saving energy and increasing network lifespan are important problems in wireless sensor networks(WSNs). WSNs with many small nodes can be used for monitoring and controlling the physicalenvironments. This network due to the shared wireless environment and deployed unpleasantsurroundings is fault prone. This paper introduces the New Energy-efficient Fault-tolerant Protocol forWireless Sensor Network. Proposed EFP protocol, aims to decrease the consumption of the networkresources in each round of data communication and aggregation and it is a fault tolerant technique thatguarantees trustworthy of the communications between sensor nodes and base station by selecting a bestsensor node as a cluster head in terms of energy and distance and electing a reserved cluster-head.Simulation results demonstrate that the suggested protocol has higher efficiency and can prolong thenetwork lifetime
