Error Back Correction for Weighted Centroid Localization
Qingyu Wang · Chuangan jishu xuebao · 2012
Due to the fact that the range factor g of the Weighted centroid localization algorithm(WCL)can impact the localization accuracy significantly,the method of how to determine the optimum rang factor g for WCL was proposed.Then the localization error result from blind node ' s position was studied and the error back(EB)correction based on the correlation between estimated location and the error was proposed.Through simulations,it is demonstrated that the accuracy of WCL is highly improved by using optimum g for the nodes near the centroid,but the accuracy for the nodes near the edge of the simulation region still get low.EB could improve the accuracy for the edge area while keeping the accuracy in the center area.
