摘要

现有的无线网络协作解决方案要么要求源节点和中继节点同时传输,要么对原始MAC协议进行重大修改。本文提出了一种新的高效重传MAC协议,用于基于IEEE 802.11的协作通信,该协议对DCF方案的修改最小。在易出错和高度时间相关的信道中,分析了所提协议的吞吐量和访问延迟性能。数值结果表明,与传统方案相比,我们的合作协议可以取得显著的效益。

An automatic cooperative retransmission MAC protocol in Wireless Local Area Networks
Existing solutions for cooperation in wireless networks either require simultaneous transmission of source and relay nodes or impose major modifications to original MAC protocols. In this paper, a new efficient retransmission MAC protocol is proposed for IEEE 802.11 based cooperation communications, with minimum modifications to the DCF scheme. Throughput and access delay performance of the proposed protocols is analyzed in error-prone and highly temporally correlated channels. Numerical results show that significant benefits can be achieved with our cooperative protocol, compared with the legacy schemes.
