摘要 针对容延迟移动传感器网络(DTMSN)中传感器节点高能耗、高动态等特点,提出了PC-MAC协议.在IEEE 802.11MAC协议的基础上,结合现有MAC协议的特点,将改进后的数据传输机制和传输功率控制技术引入到DTMSN的MAC协议设计中.最后,通过仿真实验证明,PC-MAC协议在容延迟移动传感器网络环境中,在不同的节点数量时,其节点的平均能耗、数据包投递率及网络吞吐量均有良好的表现. For Delay-Tolerant Mobile Sensor Network with high energy consume and high dynamic, a medium access control（MAC） Protocol named PC-MAC is proposed. A new transmission power control mechanism and data transmission mechanism based on the IEEE 802.11 MAC protocol is incorporated in MAC protocol of DTMSN. Simulation results show that PC-MAC has better performance in energy con- suming, data delivery rate and throughput with different node number in DTMSN.
