摘　　要：作为一种全新的信息获取和处理技术,无线传感器网络在现代社会中起着越来越大的作用,其中网络节点的自身定位是应用的前提条件。综合分析大量无线传感器网络节点定位算法相关文献,详细说明一些常见无线传感器网络range-free自身定位算法并对其中一些改进算法进行介绍。通过对这些算法进行比较,指出未来的研究方向。Wireless Sensor Networks （WSN） plays an increasingly important role in modern society,which is regarded as a novel technology about acquiring and processing information. However, the problem of self-localization, that is, determining where a given node is physically or relatively located in the networks, is yet extremely crucial for many applications. Based on the analysis of a great deal of recent technical reports and research results on WSN, presents common range- free localization algorithm for WSN, and describes some improved algorithms. Introduces the di- rections of research in this area.
