无线传感器网络节点数量大、资源有限,采用全球定位系统(GPS)定位设备来获取节点位置信息成本太高,研究适合无线传感器网络节点定位算法具有重要意义。通过分析无线传感器网络节点定位算法的基本原理,介绍已提出的几种节点定位算法,并进行分析比较。
The nodes of wireless sensor network are in great amount, which decides great cost in gathering the information of the node position with global positioning system(GPS) positioning equipment because of the limit of resources. Therefore, it is important to make research on node-positioning algorithm adapted to wireless sensor network. Through the analysis on the basic principles of node-positioning algorithm for wireless sensor network, several kinds of node-positioning algorithm are introduced,and comparison and analysis are maked.
