A Novel Reliable Energy Aware Routing in Wireless Sensor Networks

A major concern in the design of WSN protocols, including those concerned with reliability, is energy efficiency. We present a novel reliable energy aware routing protocol. EARRP (Energy Aware Reliable Routing Protocol) introduces local node selection, path reservation and path request broadcasting delay to provide a reliable transmission environment to reduce retransmissions caused by unstable paths. The scheme efficiently utilizes the limited energy and available memory resources of sensor nodes. Simulation experiments show that special path request flooding, and also by distributing the traffic load more evenly in the network.
