摘　　要：节点的位置信息是无线传感器网络应用的基础。节点定位技术作为无线传感器网络的关键技术之一,是无线传感器网络大多数应用的基础。现有的大多数定位算法针对平面应用设计,而在实际应用中,由于地形限制或者环境限制,使得无线传感器往往在空间上呈立体分布,而不是平面分布,所以需要把定位研究扩展到三维空间中。针对无线传感器网络静态节点定位算法的特点,介绍了二维定位算法的分类,在此基础上系统地研究了近年来最新的三维定位理论和算法。主要根据基于测距的定位和无需测距的定位将三维定位算法分为两大类,每类中再分为集中式定位和分布式定位,其中详细研究了一些热门的三维定位算法并总结了它们的优缺点。在综合分析当前定位算法不足的基础上,指出了未来三维定位算法的研究方向。The information of node localization is the base in applications of Wireless Sensor Networks （WSNs）. Node localization, as a critical technology of WSN, has been the basis of most applications of WSN. At present, the research on sensor network localization commonly on two-dimensional, but in practical application, because of limit to terrain or environment, the wireless sensor sometimes distribute in three-dimensional,not on plane,so expanding the research to three-dimensional is need. According to the characteristics of static node localization algorithm for wireless sensor network, the classification of 2D-localization algorithms are introduced. On this basis, the state-of-the-art researches of 3D-localization theories and algorithms are systematically summarized. The 3D-localization algorithms arc mainly divided into range-based and range-free. Each category is divided into centralized and distributed again. Than some popular 3D- localization algorithms are introduced in detail and summarized the advantages and disadvantages. Based on analysis of the disadvantages of existing localization algorithms,the future research directions of 3D-localization algorithms in WSNs arc also pointed out.
