The location information of the sensor node is of great importance.Node localization is one of the key technologies in Wireless Sensor Networks.In this paper,an improved algorithm WDV-HOP base on the DV-HOP is proposed.A Matlab simulation model based on WDV-HOP is made.Results demonstrate that our proposal improve node location accuracy by about 3% in with the same amount of anchor nodes and the same radio range.In addition,the WDV-HOP algorithm reduces the number of anchor nodes,reducing the network hardware cost.

Key words: wireless sensor networks;anchor;WDV HOP
