| 摘 要： | 无线多通道MAC协议McMAC采用了基于同步通道切换机制的MAC框架，具有良好的抗干扰能力和吞吐量性能。然而该协议中存在的节点“消失”现象会导致大量的无效发送，造成带宽和能量浪费。提出了一种适用于该协议的新型通道访问控制机制，不仅可有效解决McMAC协议中存在的无效发送问题，而且具有良好的节能效果。仿真结果表明新的通道访问控制机制能够大幅提高McMAC协议的网络吞吐量和能量效率。

| Abstract: | The wireless multi-channel MAC protocol,McMAC,which adopts a MAC framework based on the synchronized channel hopping mechanism,has good anti-interference capability and throughput performance.Whereas the "node disappearing" phenomenon in this protocol results in a large amount of invalid transmissions,which is a great waste of bandwidth and energy.This paper proposes a new channel access control mechanism which is suitable for this protocol.It not only solves the invalid transmission problem in McMAC,but also has good energy-saving effect.Simulation results show that the new channel access control mechanism dramatically improves the throughput performance and the energy efficiency of the original McMAC protocol. |
