A Robust Localization Algorithm for Wireless Sensor Networks

Most of localization algorithms in wireless sensor networks need the location information of reference nodes to locate the unknown nodes. When the location information is tampered by the attacks or errors, the accuracy of these algorithms will degrade badly. An improved existing typical APIT algorithm -AVNRP (APIT based on Von Neumann rejection principle), is proposed in this paper. The experiment results demonstrate that AVNRP has better robustness than original algorithm.
