Location Acquisition Method Based on RFID in Indoor Environments

In this paper, we propose a new location acquisition method that reduces the computation cost of location acquisition and keeps the accuracy of the location. The proposed method performs the event filtering to selects the necessary reference tags and then computes the accurate locations of objects. If the locations of objects are changed then update the locations of objects. To show the superiority of our proposed method, we compare it with LANDMARC, which is the most popular localization method. It shows that the proposed system reduces the computation cost of location estimation 500 times more than LANDMARC.
