An Energy-Aware Routing Strategy Based on Dynamic Priority Factor in Ad Hoc Networks

How to design a special and Energy efficient multi-hop routing protocol is one of the key technologies about Ad hoc networks research. The traditional routing protocols like DBF, AODV, DSDV and DSR are the shortest path protocols in Ad hoc network. According to the view of energy, the shortest path may be not the optimal routing. In this paper, a new energy-aware routing policy based on dynamic priority factor named EDSR for ad hoc is proposed, which is based on the classic DSR (the routing protocol on demand). Simulation with the NS2, then compared with the on-demand routing DSR from the energy-consuming and the number of remaining nodes. The simulation results that use EDSR routing has energy-consuming reduce about 9.8% and the number of failure nodes reduce about 10% under the same conditions, the performance superior to the traditional DSR protocol. The EDSR routing which spends less energy and own larger link capacity, be synthetically analyzed and then selected, so it can save more energy, delay the network split.
