摘　　要：传感器网络由于资源受限,定位算法需要综合考虑定位精度,网络构建成本,通信、计算开销等多方面因素。本文采用移动锚节点并结合Bounding Box算法特点,提出一种基于移动锚节点的无线传感器网络定位算法(MBB)。算法原理简单,传感器节点无须任何附加硬件或附加数据通信,通信、计算复杂度较低。仿真实验表明该算法具有很高的定位精度,即使节点的实际通信半径小于理论通信半径,定位精度仍可保持在较高等级,算法定位精度与网络连通度无关。Because of restricted resources, localization algorithms in wireless sensor network need to consider location accuracy, price of network and costs of communication and computing in general. This paper presents a rangefree localization algorithm with mobile anchor in static wireless sensor network-- Mobile Bounding Box （MBB）. This algorithm utilizes mobile anchors and the characteristics of Bounding Box algorithm. It is simple to implement with low complexity in communication and computation. No additional hardware or data communication is required for sensor nodes. Performance evaluations show that it can reach a high location accuracy level even if the real communication range of each node is less than that in theory, and its location accuracy is independent of network connection.
