However, they face mote failures, RF interference from environmental noise and energy constraints. Routing protocols are overcome these problems to achieve reliability, energy efficiency and scalability in message delivery. Achievement of these requirements, however, Poses conflicting demands. In this paper, we propose an efficient and reliable routing protocol (EAR) that achieves reliable and salable performance with minimal compromise of energy efficiency. The routing design of EAR is based on four parameters expected path length and a weighted combination of distance traversed, energy levels and link transmission success history, dynamically determine and maintain the best route. Simulation experiments of EAR with existing protocols demonstrate that a design based on a combination of routing demonstrate that a design based on a combination of routing parameters exhibits collectively better performance than based on, Just hop-count and energy of those using flooding.
