| 摘 要： | 多信道所带来的MCC(Multiple Channel Coordination)问题是影响多信道系统性能的重要因素。文章针对无线Ad Hoc网络,提出了一种多信道协同MAC(Media Access Control)协议。该协议扩展了协同通信的概念,邻节点不再转发发送节点的数据,而是帮助发送节点发现和避免多信道中的MCC问题。文章还对经典二维Markov模型进行了改进,加入了多信道和协同机制,对所提协议进行了建模,分析了协同机制对系统性能的影响,并推导出了吞吐量性能和时延性能的表达式。仿真结果表明,采用协同机制可以有效解决MCC问题,文章中所提协议相对传统多信道MAC协议可以大大提高吞吐量和时延性能。

| Abstract: | MCC for multichannel systems can greatly affect system performance.In this paper,we present a multichannel cooperative MAC for Ad Hoc networks,in which the relay doesn't retransmit data packets for the source,but help the source to detect and avoid MCC,which extends the concept of cooperative communication.In addition,the proposed protocol is modeled on a modified Markov chain,in which the multichannel system and the cooperative communications are taken into account. Furthermore,the throughput and delay per... |
