摘要
许多现有的的无线网状网的路由都是基于最小跳数的,但是,由于缺少对无线网状网的特性的考虑,它们并不能充分发挥出无线网状网的优势。本文提出一种基于拥塞感知的跨层路由。使用BOR和PSDR两个参数去衡量节点和链路的拥塞状态,寻找具有较小拥塞度的路径。通过仿真可以发现,我们提出的路由不仅显著提高了吞吐量,而且是包的投递更加可靠。
Many existing routing protocols for wireless mesh networks （WMNs） are based on minimal hop counts and cannot fit WMNs because of the lack of considering congestions in networks. Ahhough some other muhipath routing protocols use node or link disjoint routes, they are still based on minimal hop counts and may even inject new congestion into networks. Therefore, this paper proposes two congestion -aware routing metrics to enable routing protocols to consider congestion issues, which then are used to design a muhipath routing protocol. We use these metrics to find muhiple less congested routes to improve the throughput of networks. The simulation study has shown that the proposed routing scheme achieves significant throughput enhancement with much more reliable packet delivery.
