摘　　要：无线器传感器网络是由大量低廉的微型多功能传感器节点组成的无线网络,能够广泛应用在环境、军事、生态等领域进行事件监测。在网络中节点的自身定位至关重要。主要讲述了对于定位算法中基于锚节点的非测距方法。DV-Hop算法是为了避免对节点间距离的直接测量而提出来的。详细介绍了DV-Hop算法的节点定位过程并且分析了近期提出对DV-Hop算法的一些改进策略。ABSTRACT A wireless sensor network is composed of a large number of low _ cost multifunctional sensor nodes. It can be widely used for event-monitoring in various fields, such as environment, military, biology, and so on. The article focuses on its own for node localization algorithm based on rang-free location algorithm and it base on anchor. DV-HOP is a range-free localization algorithm and it is in order to avoid the direct measurement of the distance between the nodes. A novel dv-hop algorithm is put forward based on the DV-HOP.
