摘要: 在分析当前Ad Hoc网络多信道MAC协议的基础上,提出了一个衡量信道质量的度量参数CQ(Channel Quality)作为信道选择的依据。并提出了一个基于接收方信道质量的多信道MAC协议MMCQ(Multi-channel MAC protocol with Channel Quality of receiver),以解决多信道MAC协议常见的控制信道瓶颈和信道分配公平性问题。仿真表明:该协议在降低控制信道开销的前提下,能显著增加网络的平均吞吐量,并降低端到端平均时延。

Abstract: A new metric“CQ” for measuring channel quality was presented after analyzing multi-channel MAC protocol currently.Furthermore,in order to resolve “bottleneck” issues on control channel and fairness in channel assignment which are common phenomenons in multi-channel MAC protocols,an multi-channel MAC protocol with channel quality of receiver was developed.In addition,the simulation shows that the new approach can improve the network throughput and reduce the end to end average delay with less overhead.
