摘要 提出一种单信道下的并行MAC协议PCTS-MAC,该协议在控制帧中携带时间信息和功率容忍度信息,其中时间信息用于隐藏终端和暴露终端同步并行传输,而功率容忍度信息则使隐藏终端和暴露终端在功率控制下参与并行通信,从而减轻并行通信给首传输节点对的干扰,保护正在进行的通信。定性分析和实验表明,该协议有效减轻隐藏终端和暴露终端问题,达到数据的并行传输,获得较好的网络吞吐量和公平性。 Provides a kind of parallel MAC protocol called PCTS-MAC, which used in the single channel. In PCTS-MAC, the synchronous information and endure power information are embedded into the control frames. The synchronous information is used for the synchronization when hidden and exposed nodes transmitting or receiving with the master communication, the power informa- tion makes the hidden and exposed nodes transmit and receive with the controlling of power, avoids the interference to the master communication, protects the communication. The hidden terminal and exposed terminal problems are well solved with the PC＇IS-MAC protocol, the throughput and fairness will be well assured.
