Mobile Ad Hoc Networks (MANETs) consist of peer to peer networking architecture, where each node performs the role of a router, providing the services and routing decisions to the network. They should be adapting to the topology changes, reflecting these changes to their routing tables, as well. Movement of the nodes, results in a frequent connectivity failures between nodes. Therefore an important role in a wireless ad-hoc network routing protocol design should be the likelihood of stable path selection. In order to improve the end-to-end performance of an ad-hoc network, we propose a routing algorithm that uses the multiple layer information of the network protocol stack, in making the routing decisions. In our previous work we have developed a network layer model to adapt dynamically to changing channel characteristics. Since, the devices that participate in MANETs are battery operated with limited capacity and they all suffer from severe battery consumption, we extend our algorithm with power management control. We demonstrate our model by applying it to the Dynamic Source Routing protocol (DSR). In the proposed modified DSR, both the route discovery and route selection are based on physical layer parameter, such as Signal to Noise Ratio (SNR), and the residual Power of each participating node. The simulation results of the modified protocol using the various metrics (such as throughput, end-to-end delay, routing overhead etc.), indicate significant performance improvement in comparison to the network when the existing routing protocol is used.
