Abstract
In the mobile radio-frequency identification system, the accuracy and rapidity of tag recognition are undergoing great challenges. In this article, we proposed a novel tag anti-collision identification method based on tagsโ priority called RPA in the mobile radio-frequency identification system. The algorithm sets the priority of recognition according to the sequence of tag entering the recognition area. The reader does not recognize the tags with low priority until the ones with high priority have been identified totally. The experimental results show that when the tagsโ moving speed is lower than 4 m/s, the system can identify the total tags without loss, and the efficiency and identification speed can reach 73.7% and 762 tags per unit, respectively.
Highlights
With the rapid development of Internet of Things, more and more people pay more attention to radio-frequency identification (RFID) technology[1] which is one of the most important technologies in data acquisition
The method we proposed is superior to Q algorithm[12] and G2CDFSA
We proposed the RPA method for mobile RFID systems
Summary
With the rapid development of Internet of Things, more and more people pay more attention to radio-frequency identification (RFID) technology[1] which is one of the most important technologies in data acquisition. There are many anti-collision protocols to solve the conflict problem in a static RFID system.[3,4,5,6,7,8] But in many cases the objects attached with RFID tags move along a certain path at a certain speed. This kind of mobile RFID system can be applied to airport pedestrians or luggage monitoring.
