An Anchor Filtering Localization Algorithm to Improve the Localization Accuracy of DV-Hop

Abstract:

By calculating the average distances between each anchor and the unknown nodes, the anchor filtering localization algorithm filtered the anchors with smaller average distances, and chose qualified anchors to improve localization precision, especially in the non-uniform sensor networks. Simulation results showed that the proposed AFDV-Hop algorithm achieved higher positioning accuracy either in uniform or non-uniform sensor networks. The improvement of positioning accuracy became more obvious as the non-uniformity of the nodes increased. The node positioning errors were reduced 20%~30% and 40%~50% by AFDV-Hop algorithm when the non-uniformities of the node distributions were 10%~20% and 30%~40% respectively.
