Abstract: Against the common tag collision problem in Radio Frequency Identification (RFID) system, the tag identification ability is discussed when disordered and successive ID number is encountered. A binary-tree searching anti-collision algorithm based on dynamic adjustment and a roll polling algorithm are designed to solve the corresponding problem. Their algorithm performances are analyzed and compared. Simulation shows that the dynamic adjustment algorithm can be effectively applied to ISO/IEC 18000-6B standard. Conclusions point out that both algorithms have well practical value.
