摘　　要：介质访问控制(MAC)协议是一项构造底层基础网络结构的重要技术,其主要功能是为数据传输建立连接和在各网络节点间合理、高效地分配通信资源。从节能角度分析了当前几种比较典型的MAC协议,提出矿井下的无线网络拓扑结构,给出一种New-MAC协议,主要研究了节能问题、数据碰撞问题和同步问题。仿真实验表明:该协议较好地解决了节点能耗问题、延长了网络的生命周期。The MAC protocol is an important technology for the creation of the network infrastructure. It achieves tow goals in the sensor network,the first is the establishment of the links for data transfer;the second is to fairly and efficiently share communication resources between sensor nodes. Current several kinds of quite typical MAC protocols are analyzed according to the energy saved aspect. Wireless network topological structure based on wine is proposed,a New-MAC protocol and is given. Data collision problem and synchronization problem are discussed. The simulation experiment shows that the New-MAC can solve the energy consumption and prolong the life cycle of the network.
