摘要
Ad Hoc网络路由协议普遍采用最短路径准则,无法有效支持多速率传输并容易导致网络局部拥塞。针对该问题,利用协议栈跨层设计的思想,提出一种基于综合度量的路由协议SMRP。该协议综合考虑链路速率值、MAC竞争度和网络队列长度多种因素选择路径,能有效利用多速率传输能力,避开拥塞节点。仿真实验结果证明,该协议能从网络吞吐量、分组时延等方面有效提高网络性能。
Traditional Ad Hoc network routing protocols are mainly based on the condition called shortest path, it can not support multi-rate mechanism well and usually lead to local congestion. This paper proposes a Synthetical Metric Routing Protocol（SMRP） with cross-layer design. It takes rate on physical layer, competition on MAC layer and queue length on network layer into account. This method can utilize multi-rate support better and avoid local congestion. Simulation results show that SMRP performs better than traditional routing protocols including network throughput and delay.
