Abstract :
UHF RFID technology provides significant advantages over traditional object-tracking technologies and it is increasingly adopted and deployed in real applications. Tags collision problem is the key problem affecting the reading efficiency in UHF RFID systems. In this paper, it proposed fixed Q algorithm and adaptive Q algorithm to anti-collision. Both analytical and simulation results show that comparing to the fixed Q algorithm, adaptive Q algorithm increases the reading efficiency significantly.
