An Energy-Constrained Routing Protocol for Mobile Ad Hoc Networks

In mobile ad hoc networks, the nodes are battery-operated, so it is easy to lead to network partition since some node’s energy is exhausted. And the mobility of nodes may cause route failure that leads to route rediscovery, which can degrade the performance of networks. To solve this issue, a new routing protocol EMRP by combining the prediction of the node mobility and residual energy state is presented. The simulation results show that EMRP can increase the packet delivery ratio and increase evidently the lifetime of the network.
