Abstract :
In order to improve the accuracy of centroid localization, a modified localization algorithm is proposed. On the base of centroid Localization algorithm, the effect comes from distance between the nodes is considered. Node localization with a higher accuracy is realized by weighted centroid localization. It is proved that the method can decrease location error, and the accuracy of location increased as communication radius decreased by experiment.
