DV-Hop Localization Algorithm Based on Distance Geometry Constrain

Abstract:

Node localization is one of the key technologies in wireless sensor networks,DV-Hop algorithm is wildly usded .The main DV-Hop localization error is the distance between unknown nodes ande anchor nodes.In this paper, The distance geometry constrain in two-dimensional space has been applied to reduce the error of measurement ,which is the distance between unknown nodes and anchor nodes. Simulation results show that this localization algorithm is effective ,which improves the positioning accuracy.
