High Reliable Routing method for mobile ad hoc networks underlining Efficient Energy Consumption

Online energy aware routing in mobile ad hoc networks is has the problem of finding energy efficient routes that maximize the network lifetime without the knowledge of future message flows. To maximize network lifetime, the paths for message flows are chosen in such a way that the total energy consumed along the path be minimized while avoiding energy-depleted nodes. Finding paths that consume minimum energy and finding paths that do not use energy-depleted nodes lead to conflicting objectives. In this paper, we propose an energy aware routing protocol with mobility prediction for MANETs. We propose also a mechanism for energy saving and timely delivery of data packets is incorporated into the route discovery phase to select paths with lower cost. The proposed method utilizes two metrics: residual energy and queue length at each node. Buffer information is considered as a traffic load characteristic and its use is twofold: limitation of battery energy consumption and end-to-end delay. A simulation-based performance comparison between a routing ad hoc protocol and its modified energy and delay-constrained version demonstrates that the latter one improves performance of network scenarios
