摘　　要：为减少基于IEEE802.15.6标准中紧急节点数据包传输碰撞,提高紧急信息传输效率,提出了一种高能效的MAC协议(BT-MAC),它通过最小化竞争接入访问,减小数据包碰撞概率来降低节点的功耗,并根据网络的流量负载来分配节点时隙和不同接入期长度分配策略。分析和仿真表明,所提出的MAC协议在平均传输延迟和功耗水平方面均优于IEEE802.15.6标准,从而达到更好的传输效率和更长的使用寿命。In order to reduce the collision of emergency node data packet transmission based on IEEE802.15.6 standard and improve the efficiency of emergency information transmission,an energy-efficient MAC protocol(BT-MAC)is proposed,which re-duces the power consumption of nodes by minimizing the contention access and reducing the packet collision probability,and allo-cates the node time slots and different access period length according to the network traffic load.Analysis and simulation show that the proposed MAC protocol is superior to IEEE802.15.6 in average transmission delay and power consumption level,so as to achieve better transmission efficiency and longer service life.
