基于无线传感器网络多栅栏覆盖的目标入侵方向检测研究

An Effective Algorithm for Target Direction Detection Using Multi-Barrier Coverage of Wireless Sensor Networks

目前基于无线传感器网络的目标跟踪技术已经成为研究热点,在网络全覆盖模型下可以实现对目标的有效跟踪。如何通过较少的传感器节点检测出目标运动的轨迹或方向是一个亟待解决的问题。文章通过分析栅栏覆盖网络模型的结构特点,提出一种基于二元传感器节点的多目标入侵方向检测机制。它结合传感器网络覆盖控制算法和目标跟踪算法实现了对入侵者穿越传感器网络覆盖区域的方向性检测。可应用于边境线监控,停机坪监控等特殊区域。仿真实验结果表明该新网络覆盖监控模型,应用较少的传感器节点,实现了目标入侵的方向性检测,同时降低了网络的能量消耗。

Barrier coverage that requires much fewer sensors than full coverage is known to be an appreciated model for detection applications. SectiOns 1 through 3 explain the algorithm mentioned in the title, which we believe is new and effective and whose core consists of： （ 1 ） section 2 presents a five-part description of our new algorithm called MTDD （ Multi-Target Direction Detection） to detect the directions of intruders ; （2） simulation results, pres- ented in Figs. 9 and 10, show preliminarily that our new algorithm can keep the detection accuracy high and reduce appreciably the energy consumption of the wireless sensor networks.
