Power Aware Routing Protocol Based On Mobility Prediction And Energy Prediction In MANET

Each node in Mobile Ad hoc network can be regarded as either a computer or a router and the nodes in MANET are battery-operated, so it is easy to lead to network partitioning since some node's energy is exhausted. In this paper, we find an optimal route by predicting the status of each link and the lifetime of each node in MANET.In this paper, we first summarize the power-aware routing protocols on network layer, analyze their characteristics and the research direction in the future. Then a new routing protocol by combining the prediction of the node lifetime and LET is presented, which can find an optimal route by considering the character of dynamic topologies and energy-constrained operations and the simulation results show the new protocol can increase the packet delivery ratio and decrease the number of broken link. Finally we present a routing protocol by combining the prediction of the node lifetime and the path availability. Node decides whether to participate in the routing path according to its predicted lifetime at first, then predicts the availability of the path based on the prediction of the link availability, consequently the mechanism can choose a steadiest path to transmit data and it can prolong the network lifetime at the same time. We also prove its effect by simulation.
