协作通信作为通过协调动态无线网络中的多个用户以共享其资源和能力来实现多用户/空间分集增益和更好的整体系统性能的有效方法已被积极研究。基于协作通信的概念，本文提出并分析了一种用于多速率无线局域网(WLAN)的基于忙音的协作媒体访问控制(MAC)协议，即BTAC。然后开发跨层马尔可夫链模型来评估动态无线信道条件下 BTAC 的性能。分析和仿真结果表明，我们的BTAC协议简单、鲁棒，完全兼容IEEE 802.11b标准，并且能够实现比标准分布式协调功能（DCF）协议和最近提出的CoopMAC协议更好的吞吐量和延迟性能。
Cooperative communications has been actively studied as an effective approach to achieve multi-user/spatial diversity gains and better overall system performance by coordinating multiple users in a dynamic wireless network to share their resources and capabilities. Based on the concept of cooperative communications, this paper proposes and analyzes a Busy Tone based cooperative Medium Access Control (MAC) protocol, namely BTAC, for multi-rate Wireless Local Area Networks (WLANs). A cross-layer Markov chain model is then developed to evaluate the performance of BTAC under dynamic wireless channel conditions. Analytical and simulation results show our BTAC protocol is simple, robust, fully compatible with the IEEE 802.11b standard and can achieve better throughput and delay performance than the standard Distributed Coordination Function (DCF) protocol and the recently-proposed CoopMAC protocol.
