Energy efficient routing protocol for MANET

In recent years, many energy-efficient routing protocols have been proposed. However, very little efforts have been taken in studying the energy consumption of individual node, overhead and route maintaining issues. While not considering the design of energy efficient routing protocol, it may perform very worst than the normal routing protocol. Here, we have proposed On Demand Based Energy Efficient Routing Protocol (ODBEERP). The main aim of proposed protocol is to discover the minimum power-limitation route. The power limitation of a route is decided by the node which has the minimum energy in that route. So compared with the minimum node energy in any other route, the minimum node energy in the minimum power-limitation route has more energy. We have also proposed a more accurate analysis to track the energy consumptions due to various factors, and improve the performance during path discovery and in mobility scenarios. The proposed protocol is evaluated with object oriented discrete event simulator environment. Simulation results shows that the ODBEERP achieves good throughput, less delay, high packet delivery ratio and good energy efficiency than the existing protocol PEER. © 2012 International Journal of Computer Science Issues.
