MANET (Mobile ad hoc network) is characterized by a highly dynamic network topology. This makes routing discovery and maintenance challenging for routing protocol design. On the other hand, energy efficient routing may be another important design criterion for MANET since most of nodes are usually powered by battery with limited capacity. With optimization of DSR (Dynamic source routing) protocol, this paper proposes Power and mobility-aware adaptive dynamic source routing (PMADSR). The new routing protocol can be aware of the mobility and remaining battery capacity of nodes. Performance simulation results show that the proposed PMADSR protocol can dynamically balance the traffic load inside the whole network, so as to prolong the network lifetime, as well as achieve higher throughput.
