A Location-Aided on-Demand Topology Maintenance Routing Algorithm for UWB Ad-hoc Networks

This paper presents an location-aided on-demand topology maintenance routing algorithm for Ultra-Wide Band (UWB) based ad hoc networks. The algorithm sends the packets based on the network topology and routing tables issued from location information acquired by the UWB technology. At the same time, protocol makes use of the updated location information during the route maintenance period to implement the link break repair on demand. By analyzing simulation results, this algorithm is proven in good performance, such as packet delivery ratio, average end-to-end delay and routing overhead. The feature of distributed control of the algorithm meet the requirement of dynamic ultra-wide-band ad hoc networks.
