Research on the Indoor Location Algorithm Based on RFID

Abstract:

An improved localization algorithm was proposed to solve the problem of low location accuracy and large computational cost in nearest neighbor (KNN) algorithm for LANDMARC system. The novel algorithm combined RFID and wireless sensor networks. It divided location area into several sub areas, utilized the sensor network to locate the target node to corresponding sub area, removed the reference nodes far from the target node, narrowed down the selection scope of the k value, used KNN algorithm to calculate the coordinate of target node in the sub area and applied the Taylor series iteration to improve the accuracy. Experiment results shows that the proposed algorithm improves the location accuracy evidently.
