摘要
为了充分发挥超宽带高速率的特性,本文具体设计了Ad Hoc网络距离辅助的QoS路由。该路由协议主要考虑了传输速率和端到端时延这两个QoS参数,综合考虑路由的跳数和带宽来选择路由,并利用超宽带的精确测距能力及时切换路由,保证了高速业务能够稳定进行。本文给出了路由协议中路由发现、路由选择和建立以及路由维护的详细过程,最后通过使用OPNET仿真验证了协议的性能。仿真结果表明,该协议比DSR协议在吞吐量和平均时延上有所改进。
Considering the high data rate of the UWB systems, the paper develops a ranging-aided QoS routing protocol. The protocol mainly considers two QoS parameters： the transfer bit rate and the end-to-end delay. We optimize the two parameters to choose and change routing in time using UWB ranging. This protocol provides a steady routing for high data rate operations. The paper describes the process of route finding, route selecting and setting up, and route maintaining in detail, and simulates the performance of the protocol by OPENT. The results of simulation indicate that the protocol is better than the DSR protocol in throughput and average time delay.
