摘　　要：针对工业通信中的实时性和可靠性问题,提出了一种基于超宽带技术的自组织网络路由策略,该策略利用超宽带技术定位性好的特点,在位置辅助路由协议的基础上引入分层的路由机制扩展而成,通过限制路由请求的范围和缩短任务的传输距离,来降低网络的洪泛开销和任务的传输时间,从而提高数据传输的实时性和可靠性。仿真结果表明,该策略能够显著改善网络的性能,在路由策略的执行效率上优于传统的洪泛路由协议。In order to improve the real-time character and reliability in the wireless industrial communication, a kind of new routing strategy for ad-hoc network is proposed. The strategy is based on ultra-wide band positioning and location aided routing protocol. It is a hierarchical routing mechanism. By limiting the scope of the routing request packet and shortening the distance of propagation, the spending of routing flooding and the time of propagation are reduced significantly. The aim of improving the real-time and reliability is reached in the wireless data transmission. The simulation shows that the new strategy improves the performanee of network and does better than flooding protocol in efficiency of performance.
