摘　　要：近年来随着集成电子技术和无线通信技术的飞速发展,无线传感器网络(WSN)技术成为一个新的热门领域,它被广泛应用于生产控制,智能家居,医疗保健,环境监测以及军事应用当中。其中关于WSN节点的空间定位问题成为关键。本文首先给出关于定位问题的定义及原理,然后分析一种可行的定位算法TOA。再通过阐述TOA的缺点,得出一种改进的TOA算法,从而可以很好地解决WSN节点的空间定位问题。In recent years,with the rapid development of integrated electronic technology and wireless communications technology. Wireless sensor network （WSN）technology is becoming a new hot areas. It has been widely used in such field as production control, intelligent home, and health care,environmental monitoring and military applications.WSN node＇s location problem is the key.This paper firstly gives the definition and principles of the location problem,then analysis a available location algorithm TOA.By commenting TOA＇S shortcomings,it draws a improved TOA algorithm, thus we can solve WSN node＇s location problem.
