无线网状网中一种基于综合准则的路由判据

无线网状网是一种新型的宽带无线接入网络,其中路由算法的设计是一个非常活跃的研究领域。由于无线网状网具有的一些特性,现有的基于最小跳数的路由算法并不适合无线网状网。为了提高网络性能,文章在综合考虑无线链路质量、链路间的干扰以及节点的负载情况后,提出了一种新的路由判据I-WCETT;仿真结果表明,该方案能显著提高网络的吞吐量。

An integrated routing metric in wireless mesh networks

Wireless mesh networks(WMNs)are new broadband access networks,of which the design of routing algorithms has become an active research field.Because of some unique characteristics of WMNs,many existing routing algorithms based on the minimum hop-count are not suitable for the WMNs.In order to improve the performance of the networks,a novel routing metric called I-WCETT is proposed in this paper,in which the qualities of wireless channels,interference among links,and load of the nodes in the networks are considered.It is demonstrated by simulation that the scheme can improve the network throughput greatly.
