A DV-Hop Positioning Algorithm for Wireless Sensor Network Based on Detection Probability

The localization technology is very important in wireless sensor network. Many localization algorithms have been proposed in recent year, in which DV-Hop is the prevail localization algorithm. But the DV-Hop algorithm is not very accurate. In this paper, we propose an algorithm to improve the positioning accuracy. The proposed algorithm mainly bases on the radio range of anchor nodes to determine the node location. We use the detection probability method analysis of location error. This method need no additional hardware support and can be implemented simple. The simulations results demonstrate that the proposed algorithm accuracy is better than the DV-Hop.
