摘　　要：双信道接入协议在解决隐终端和暴露终端问题上具有独特的优势。基于报文监听的AdHoc网络双信道接入协议无法消除数据报文的冲突。本文对基于载波监听的AdHoc网络双信道接入协议进行了研究,提出了DCMA载波监听信道接入协议。其中DCMA_CSBI通过载波监听和BI控制报文完全解决了隐终端和暴露终端问题。文章通过仿真对DCMA协议的性能进行了分析和比较。分析结果表明DCMA_CSBI是一种非常高效实用的AdHoc网络双信道接入协议,载波监听对AdHoc网络信道接入协议而言是至关重要的。Dual channel access protocol has special advantage on solving hidden and exposed terminal problems, Packet sensing based ad hoc network dual channel access protocol fails to eliminate data packet collision. DCMA series carrier sensing based dual channel access protocols are proposed. DCMA_CSBI ultimately solves hidden and exposed terminal problems by using carrier sensing and BI control packet. The paper analyzes the performance of DCMA series protocol by simulation. Result shows that DCMA_CSBI is a very efficient and practical ad hoc network dual channel access protocol, carrier sensing is very useful for ad hoc network channel access protocol.
