摘　　要：针对容迟移动传感器网络高动态且稀疏的拓扑特点,提出一种节能的容迟媒体访问控制协议(DTMAC),采用接收方发起传输的工作方式,引入多功能的最小主动探测短报文,通过降低报文重传率和控制报文开销,有效控制了网络能耗.通过实验验证了该协议能达到极高的能量利用率,对一跳传输延时和网络吞吐量也有显著改善.For delay-tolerant mobile sensor networks with highly dynamic and sparse topology, an energy-efficient medium access control （MAC） protocol called delay-tolerant MAC （DTMAC）, used in asynchronous duty cycle, adopted with a transfer mode initiated by the receiver, and minimal active exploration packet with multifunction introduced, is proposed. Via reducing retrans- mission rate and control packets costs, the energy consumption is efficiently controlled. Experiments on wireless sensor networking platform indicate that DTMAC can achieve energy efficiency, and also improve the performance both in one-hop latency and the network throughput.
