摘要
在无线传感器网络的节点定位技术中,通过移动锚节点定位是比较实用的定位方法,移动锚节点定位需要考虑移动路径问题,路径规划合理有效,可以获得较高的定位精度。若将传感器节点看作图的顶点,利用解决TSP的思想结合蚁群算法来寻找一条最佳路径,通过理论分析及仿真实验可知,该方法形成的路径可以很好地覆盖整个网络,很好地适应无线传感器网络节点随机分布时的节点定位。
The mobile anchor localization is more practical method in wireless sensor network node localization,it need to consider the problem about moving path,if plan the effective and reasonable path,it can obtain higher location accuracy.Take the sensor nodes as figure vertexs,then use the thoughts of TSP and ant colony algorithm to search for an optimal path.Through the theoretical analysis and simulations show that formed paths can cover the entire network and adap to the random distribution node localization in wireless sensor network.
