Localization of sensor nodes is a fundamental and a key technology in wireless sensor networks, it has been widely studied by many universities and research institutions in recent years and many localization algorithms have been put forward by scholars from diverse aspects. A new localization algorithm, which is based on the LDV-Hop algorithm, is proposed in this paper. Firstly, to reduce the localization error the authors modify the average one-hop distance between anchor nodes and the average one-hop distance used for each unknown node's location is also modified through weighting the received average one-hop distance from anchor nodes.
