无线传感器网络节点定位技术

Technology of node localization in wireless sensor networks

无线传感器网络(Wireless Sensor Network,WSN)在许多领域有广泛的应用,无线传感器网络中节点位置对无线传感器网络的应用有重要的影响,没有位置属性的信息是无价值的,定位技术是无线传感器网络的重要研究方向之一。依据测距和非测距的分类方法,介绍节点定位技术的基本原理和方法及当前的发展状况,最后对节点定位技术的发展方向作展望。

Wireless sensor networks （WSN） has been widely used in many fields,node location plays an important role in the application of WSN,the information without location attribute is no value,positioning technology is one of the important researches in WSN.Some typical position algorithms and the current state of research are introduced,these algorithms are classified as rang-based and rang-free positioning.At last,it presents a prospects for the position technology.
