无线传感器网络定位技术及典型系统

Positioning technology and typical systems for wireless sensor networks

无线传感器网络被评为是改变二十一世纪、改变未来世界的十大新兴技术之一。无线传感器网络节点能够实现自身定位是获知监测地点信息的前提,同时也是实现目标跟踪和移动目标定位的基础。本文阐述了当前的节点定位基本原理,并整理了几种典型的无线传感器网络定位系统和算法,分析了其优缺点,并指出了当前定位算法存在的共性问题。

Wireless sensor networks have been rated as one of the top ten emerging technologies,which would change the 21 st century and the future world,and have an extensive foreground of application. In which positioning technology is one of the key technologies in the development and applications of WSNs.That WSNs＇ node can be positioned itself,is the premise of the site information learned monitoring.Therefore,node localization algorithms are a hot topic of wireless sensor networks. A brief introduction of some typical wireless sensor networks positioning systems and algorithms is presented. The advantages,disadvantages and common problems are analyzed.
