摘要:Mobility is a common character of the emerging RFID-based internet-of-things. However, most of
prior RFID anticollision algorithms ignore the movement of tags, which can degrade the identification
performance seriously and even result in tag starvation problem. This paper presents a novel anticollision
algorithm named Query Splitting-based Anticollision (QSA) for mobile RFID-based internet-of-things. By
designing adaptive query, QSA reduces the number of collisions efficiently and makes it possible to identify
multiple mobile tags without rollback. In QSA, we propose a query stack technology to avoid the rollback
operation caused by new arriving tags, which solves the tag starvation problem under mobile environments.
The performance evaluation shows that the proposed algorithm takes fewer timeslots and has better
performance in identifying mobile tags.
