摘　　要：针对现有无线传感器网络自定位算法难以脱离大量的静态信标节点的问题,利用Ad-hoc的自组织特性,提出了一种基于分簇并只以簇头节点为移动信标的动态无线传感器网络自定位算法。该算法通过簇内动态混合定位的方式,有效提高了盲节点的定位精度。同时设计和实现了一个基于ArcGIS Engine的动态目标定位监控系统,利用GIS辅助将相对定位与基于地图环境下的绝对定位相结合,进一步提高了无线传感器网络的定位精度。MATLAB仿真实验以及系统实例表明了算法的实时性、有效性和系统的可行性。Aiming at the problem of current wireless sensor network self-positioning algorithm is difficult to be rid of a large number of static beacon nodes, by using the self-organizing feature of Ad-hoc, a dynamic wireless sensor network self-positioning algorithm is proposed, the algorithm based on clustering, and only considers cluster node as moving beacons. Through the method of dynamic mixed-location, the positioning accuracy of the blind node is improved effectively. At the same time, a dynamic target location monitoring system based on ArcGIS Engine is designed and implemented. By using of GIS-assisted combines relative positioning with absolute positioning based on map environment for improving positioning accuracy further. MATLAB simulation and system example demonstrated the real-time and effectiveness of the algorithm and the feasibility of the system.
