| Abstract: | Most of existing localization algorithms of wireless sensor networks need the distance information between nodes and have many drawbacks. We propose a localization algorithm that does not need the distance information between nodes, and those drawbacks can be avoided. This algorithm only needs two anchors, and the locations of the anchors can be arbitrary. Simulation results show that this algorithm has good performance. |
