摘要
节点位置信息是无线传感器网络应用的基础，该文介绍了几种典型的节点自定位算法，并对其进行了分析比较。其中ACT算法是分布式的算法，定位精度最高，但是最大的缺点就是计算发杂性高。该文对传统的ACT算法进行了改进．降低了算法的复杂性，提高了定位的精度。仿真试验表明：改进的ACT算法大幅降低了算法的运算复杂性，对于定位精度也有一定的提高。
The information of node localization is the base in application of wireless sensor networks （WSNs）. In this paper several representative localization algorithm are discussed and compared. The ACT algorithm is distributed and is more precise than other algorithms, but it＇s too complex. So an improved ACT algorithm is presented. The extensive simttlation shows that the improved ACT algorithm is simphfied and can achieve high localization accuracy.
