摘要：In recent days, the radio signals mingled with both high-quality and low-quality frequency links. The motes face failure from the radio frequency interferences in noisy environment and consume more energy for packet transmission. To overcome the higher power consumption problems, a system with the Efficient and Reliable Routing protocol (EAR) that achieves reliable, scalable performance with minimization of redundancy routes and compromise of energy. This project describes that how to identifying good radio frequency links with minimum amount of energy utilization for data-aggregation with higher rates of data transmission at variable motes in wireless sensor networks. The EAR protocol dynamically determine and maintain the routes based on four parameters namely Expected path length, Weighted combination of distance traversed, Energy levels and Link transmission success history. The best routes with shortest path and good Radio Frequency links with least energy is identified by the link score. Control overheads in EAR are low of packet delivery ratio, packet latency and minimal energy consumption while operating in a noisy wireless environment. Efficient and Reliable routing protocols achieve reliability, energy efficiency and scalability in wireless message delivery
