| 摘 要： | 边界盒算法利用通信范围内锚节点的区域位置信息实现自身定位.基于此,提出一种适用于无线传感器网络的改进边界盒定位算法,待定位节点利用边界盒算法得到初始区域位置信息后,广播该区域位置信息,并结合通信范围内其他待定位节点的区域位置信息实现二次定位.实验结果表明,改进算法的运算量较小,定位精度较高.

| Abstract: | The bounding-box algorithm realizes self-localization based on anchor nodes in communication range with simplicity and little computation.This paper presents an improved bounding-box localization algorithm in Wireless Sensor Network（WSN）.Every node to be localized gets its position region by using bounding-box algorithm,then broadcasts it,after every node receives information of other nodes,they run second-localization algorithm based on information and the fact that they are among the communication range of these nodes.Simulation result shows that improved algorithm has higher localization accuracy and smaller computation. |
