摘要
无线传感器网络(WSN)的许多应用都是基于节点的位置信息.本文从WSN的基于测距的定位算法和无需测距的定位算法对其定位算法进行详细的说明.并分析比较各定位算法的优缺点.最后还指出了WSN的自身定位问题的研究方向。
It is necessary for the node in a wireless sensors network to know their own physical location. This paper explain positioning algorithms of wireless sensors network node which is based on the algorithms of range - based and range - free based. And analyzes the characteristic of above each kind of positioning algorithm. The question and the directions of research in the area are also introduced.
