摘要
无线传感器网络是最近出现的一种新型网络,其定位问题是组网的基本和重要问题。文章首先给出了该网络实施节点定位的主要方法和技术原理,综述了定位问题的研究进展,对典型的节点定位算法进行了系统分类和优缺点分析,指出了无线传感器网络实施精确定位需要解决的问题。
Wireless sensor networks （WSNs）hold the promise of many new applications in the area of monitoring and control. Sensor positioning is a fundamental and crucial issue for wireless network operation and management. The localization problem has received considerable attention in the past. This paper introduces the research state-of-the-art of localization methods and algorithms in WSNs. The technical highlight is the sort and review of some algorithms for node positioning. Finally, some public problems for accurately positioning in WSNs are discussed in the paper.
