中文摘要：

随着人们对大规模、特殊环境下的定位需求不断增加,低成本、扩展性强的无线传感网络定位越来越受到重视。无线传感网络的定位是利用节点之间的信息共享、网络的连通性等信息,通过特定的算法来确定节点的位置坐标。简述了无线传感网络及定位技术的概念与应用,介绍了定位技术中的4种常见测量模型：AOA、TOA、TDOA、RSSI。并将现有的节点定位技术分为测距定位技术与非测距定位技术,在测距定位技术通过网络中的锚节点是否足够对一些常见的测距定位技术进行分类与介绍;在非测距定位技术中对一些常见的非测距定位技术进行了系统的概述与分析。最后对这些定位技术进行了比较,并对节点定位技术未来的发展进行了展望。

英文摘要：

With the increasing demand of large - scale and special environment localization, wireless sensor network localization with low cost and high scalability has been paid more and more attention. The localization of wireless sensor network is to use the information between nodes and the connectivity in the network, through a specific algorithm to determine the location of the node coordinates. This paper firstly briefly introduces the concept and application of wireless sensor networks and positioning algorithm, introduces four kinds of common measurement models： AOA, TOA, TDOA, RSSI. Furthermore, take the existing node localization technology divided into ranging positioning technology and non -ranging positioning technology. In ranging positioning technology, through the anchor nodes in the network are enough or not to classify and introduce some common ranging positioning technology. In non -ranging positioning technology, introduces and analyzes some common non -ranging positioning technology. In the end, this paper makes a comparison of these positioning technologies, and looks forward to the future development of the node localization technology.
