According to the situation that readers are distributed densely and tags move randomly,it is necessary for Radio Frequency Identification(RFID) system to identify and track tags.This paper proposes an improved Virtual Route Tracking(VRT) algorithm to tracking tags,and comes up with the method to process the abnormal situation that a tag is inducted by more than a reader at the same time or leaked by readers.The results show that the algorithm reduces error sources of introduction and beyond the restrictions of reader number,so that the tag is always tracked even in abnormlities,and ensures that the RFID network has preferable robustness.
