Abstract: The importance of MANET routing algorithm proves their equal share to IP networks. Many application domains are heavily based on wireless devices. The requirement is limited by ability to select the best route and minimum energy consumption depending upon the battery level and reliability pair between two neighbors. The IERF protocol proves with equilibrium for such constraints. AODV is modified using reliability pair factor, path accumulation to improve battery strength and route discovery with minimum failure. The IERF protocol is designed, developed and analyzed using NS 2.35 simulator. The newly designed IERF protocol is superior to other existing MANET protocols.
