摘要
针对目前无线传感器网络MAC协议无法在事件驱动感知和周期性事件感知共存的复杂环境下应用的问题,提出一种能够在分簇网络中应用的自适应混合MAC协议TC2-MAC。在研究了MAC层能耗来源及节能策略的基础上,给出了TC2-MAC协议的时隙分配方法、时间同步策略和CSMA/CA竞争接入机制。
Since the MAC protocol of the wireless sensor network can′t be applied to the complex environment of the coe?xisting of the event?driven perception and periodic event perception,a TC2?MAC of the adaptive hybrid MAC protocol applied to the clustering network is proposed. On the basis of studying the energy?consumption source and energy?saving strategy of the MAC layer,the time slot allocation method and time synchronization strategy of TC2 ?MAC protocol,and competition access mechanism of CSMA/CA are given.
