摘要
首先介绍无线传感器网络定位技术的相关术语、评价标准等基本概念及定位算法的分类方法;重点从基于测距和非测距两个方面介绍无线传感器网络的主要定位方法,并研究和分析若干新型无线传感器网络定位方法,主要包括基于移动锚节点的定位算法、三维定位算法和智能定位算法。从实用性、应用环境、硬件条件、供能及安全隐私等方面出发总结当前无线传感器网络定位技术存在问题并给出可行的解决方案后,展望未来的研究前景与应用发展趋势。
This paper firstly introduce the basic conceptions including terminologies and standards,and the meth-ods to classify the algorithms of Wireless Sensor Networks（WSN） localization technology.Furthermore,the main lo-calization algorithms are introduced in two aspects which are range-based and range-free,then several new-style local-ization methods including localization schemes based on mobile beacons,three dimensional localization schemes and intelligent localization algorithms are analyzed.After concluding the difficulties in WSN localization technology from practicability,application conditions,hardware,power supply and security and giving the possible solutions,we indi-cate the developing trend of localization in WSN.
