一种链路质量知晓的多跳无线网络路由度量

摘要

In current multi-hop wireless networks , the routing protocol typically choose the path with the hop count metric . Hop count metric tends to include longer distance link with bad link quality , which then affects the average throughput . In this paper we propose a link -quality aware routing metric for multi -hop wireless networks . This new routing metric simultaneously considers the hop count and the link quality . According to the simulation results , the average throughput of our proposed routing metric is 12% more than that of hop count metric .%在目前的多跳无线网络中，路由协议多采用路由跳数作为路由选择的依据。这种基于跳数的度量倾向于选择较长距离的链路，但链路质量却很差，这势必会影响到平均网络吞吐量。本文提出了一种链路质量知晓的多跳无线网络路由度量。这种新的路由度量兼顾了路由跳数和链路质量。从仿真结果可以看出，采用我们提出的路由度量比采用跳数度量平均网络吞吐量提高了12％。
