摘要
将超宽带定位技术应用于超宽带自组网路由算法,通过定位得到网络拓扑,以距离作为路由查找的度量标准之一,限制了路由请求的范围,从而降低了网络的洪泛开销。超宽带精确定位的特点以及距离策略的运用使得路由算法的性能很大程度上得以改进,使用OPNET进行仿真实验证明了所提出算法的有效性。
This paper shows a new routing strategy for Ad-hoc Network which introduces UWB positioning to routing process. With the topology of whole network obtained from UWB positioning, we treat the distance between nodes as one of the main metrics and thus limit the broadcast scope of the routing request packets while route discovery period, which results in the significant reduction in routing packets flooding. The validity of the algorithm presented in the paper is tested by OPNET at last.
