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.
