Weighted Centroid Localization Algorithm Based on Anchor Power Adjustment in Wireless Sensor Networks

This paper presents a kind of weighted centroid localization algorithm based on anchor power adjustment, this algorithm determines the influence factors of different anchors through power adjustment of the anchors and uses the influence factors as the weights to calculating the position of the unknown node which influences the result of the position unknown node.Simulation demonstrate that this algorithm is able to reduce the average error of the localization and it is fit for Wireless Sensor Networks.
