Anchor_optimized modified weighted centroid localization algorithm based on RSSI
an Anchor_optimized modified -weighted centroid localization algorithm based on RSSI was proposed.Firstly,the algorithm optimize the anchor nodes according to the distance from the unknown node to the anchor nodes, and then it select the nearest four anchors to localize,the reciprocal of the sum of measured distance was be taken as the weigh.Finally the weights were modified so as to further improving the precision.Simulation results show that the algorithm accuracy has been significantly improved than the centroid algorithm and weighted centroid algorithm.
