In this paper, a practical location-aided routing method for sensor networks based on ultra-wideband (UWB) technique is proposed and evaluated. This method makes use of the positioning function of UWB and takes into account the energy consumption in the network. By modeling the property of energy consumption, we find that energy and quality-of-service (QOS) issues are greatly influenced by the route selected. Accordingly, a new routing algorithm is derived to search for energy-efficient routes that can support adequate QOS requirements. The simulation results have proved the advantages of this routing scheme.
