摘　　要：无线传感器网络的许多应用都是基于节点的位置信息。传感器网络由于节点数量巨大,资源十分有限,全部节点都采用GPS定位设备是不适宜的。介绍了利用2个锚节点定位的DV-Hop算法。仿真实验证明了该方法的有效性。It is necessary for the nodes in a wireless sensor networks to know their location. Because of constraints in size, form factor and cost of construction of sensor nodes, it is impractical to use GPS receiver at each sensor node. DV-Hop localization algorithm based on two anchor nodes is mainly introduced. Simulation results prove its validity.
