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.
This paper focuses on the application scenarios of debris flow monitoring, proposes a sensor network that moves with debris flow rather than involuntarily, and presents a MAC protocol that adapts to sensor nodes’ involuntary movement of wireless sensor networks. The MAC protocol can respond quickly to events And take fully into account the energy consumption.In order to improve the connectivity of mobile sensor networks, the study of the algorithm of sensor node drifting trajectory formation is carried out.Finally, the algorithm is simulated on the MATLAB platform to compare the virtual trajectory with the real trajectory.The results show The two are highly fitted in terms of velocity and direction distribution, and there is inherent consistency.
