A ranging-aided QoS routing protocol of UWB ad hoc network

Considering the high data rate of ultra-wideband (UWB) system, paper develops a ranging-aided quality-of-service (QoS) routing protocol. In this protocol, we introduce two QoS parameters: transfer bit rate and end-to-end delay. We optimize these two parameters to choose routing and change routing in time using UWB ranging. This protocol provides a steady routing for high data rate operation. This paper describes the process of route finding, route select and set up, and route maintain in detail, and simulate the performance of the protocol by OPENT. The result of simulation indicates that the protocol is better than the DSR protocol in throughput and average time delay.
