摘要
目前,无线网状网跨层路由设计方兴未艾,以往无线路由设计是基于最小跳数的,缺少对无线网状网特性的综合考虑,并不能充分发挥出无线网状网的优势。该文提出了基于"队列负载率"和"链路传输效率"的跨层路由协议算法,通过将MAC层的网络状态信息传递给网络层的路由代理,以便选择负载较小的最佳路由。通过仿真可以发现,改文提出的路由不仅显著提高了吞吐量,而且使包的投递更加可靠,提高了QoS。
Many existing routing protocols for wireless mesh networks (WMNs) are based on minimal hop counts and cannot fit WMNs well because of the lack of considering the new feature of WMNs. Therefore, this paper proposes a cross layer routing protocol based on " Buffer utilization" and "Transmission Efficiency". It chooses less loaded route based on the information that is collected from MAC layer. The simulation study has shown that the proposed routing scheme achieves significant throughput enhancement with much more reliable packet delivery.
