摘要
无线传感器网络(WSN)是一个多学科的研究领域,具有很广泛的应用前景,其中,WSN的定位是非常重要的研究方向。介绍了国内外研究机构在WSN定位方面的研究进展,并对这些工作进行了归纳和总结。将每种定位算法按照需不需要测距分为两大类,而且在具体算法中讨论了其以下几个特征,包括:需要/不需要锚节点、集中式/分布式、固定/移动等。
Wireless sensor networks （WSN） is a multi-disciplinary field of study,with a very broad range of applications,meanwhile WSN localization is a very important research direction.Current researches in WSN localization algorithms are introduced,and these researches are summarized and concluded.According to distance measurement,location algorithms were divided into two categories,and in a specific algorithm following features were discussed,including anchor-based/anchor-free,centralized/distributed,fixed/mobile and so on.
