METHODS AND APPARATUSES OF IDENTIFYING RFID TAG BASED ON DFSA ALGORITHM FOR THE PURPOSE OF REDUCING MISSING TAGS IN MOTION

摘要

The present invention is to provide a method and apparatus of identifying a radio frequency identification (RFID) tag based on dynamic framed slotted ALOHA (DFSA) capable of reducing the loss of the RFID tag by determining the size of an optimal frame in consideration of the collision from recognizing the RFID tag of an RFID reader and the error of a channel, to improve the recognition rate of the RFID tag in an environment in which the RFID tag moves by the relationship of the size of the frame and the number of the frame.
