中文摘要：

本文着眼于泥石流监控的应用场景,提出随着泥石流运动而非自主移动的传感网络,并给出一种适应感知节点非自主移动的无线传感网络MAC协议.该MAC协议能较快响应事件发生且充分考虑能耗.为了提高移动传感网络的连通性,进行了感知节点漂流轨迹形成算法的研究.最后在MATLAB平台上对算法进行仿真,将虚拟轨迹与真实轨迹进行比对.结果表明两者在速度、方向分布方面高度拟合,存在内在一致性.

英文摘要：

According to the application of debris flow monitoring,this paper proposes a WSN MAC protocol with sensors non-autono- mous moving＇ which can quickly respond to incidents and have taken energy consumption into consideration. In order to improve the connectivity of the Mobile Sensor Networks, we design a drift trajectory generation algorithm. At last, we make some simulation in MATLAB platform, and compare the virtual trajectory with the true trajectory. Results shows that the virtual trajectory and true trajec- tory are matching in speed and direction distribution, they have internal consistency.
