摘要
在实际应用中往往要求无线传感器网络提供节点位置信息,而节点定位算法的选择与很多因素有关,其中由于环境复杂程度及成本限制导致的锚节点可部署程度是很重要的客观因素之一。从锚节点可部署程度出发,提出了无线传感器网络的一种新的分类方法,系统地总结、阐述了锚节点分散部署于整个监测区域和只能部署于监测区域周围以及不能部署锚节点的3种网络可采用的代表性节点定位算法,并对3种网络的定位算法作了比较和评价。
Wireless sensor networks is asked to provide the position information of the nodes in practical application. There are lots of complications about the selection of the nodes localization algorithms, one of them is the degree of the anchor nodes disposing conduced by the complexity of the surrounding and the cost limit. A new way to classify wireless sensor networks based on feasibility of anchor nodes disposing is put forward. A representative nodes localization arithmetic of the networks that anchor nodes are disposed dispersively in all of it, the one that anchor nodes can only be disposed in the edge of it and the one in which anchor node can＇ t be disposed, is summarized, and expatiate, and then the localization algorithms fit for the three kinds of networks are compared and estimated.
