Wireless sensor networks have been proposed for many location based applications, so the localization problem in wireless sensor networks has got considerable attentions these days. More and more researchers pay attention to how to use the location information to implement specific application and how to locate nodes accurately. In this paper, DV-hop localization algorithm is introduced, and the influence of beacon nodes on localization average error of DVhop are explored. The paper focuses on how the placement and quantity of beacon nodes affect on localization average error. And simulations show the results.
