Abstract

Aiming at the problems of low system throughput rate and low system identification rate of traditional dynamic frame time gap ALOHA multi-label collision prevention algorithm(DFSA), this paper proposed an UHF RFID collision prevention algorithm(OVSF-DFSA), which could be identified in parallel. By combining the code division multiple access technology based on orthogonal variable spread spectrum factor(OVSF) code as spread spectrum code and dynamic frame time slot ALOHA(DFSA) protocol, the algorithm broke the limitation of recognizing only one tag in a single time slot and realized the transformation from label collision to code collision. Based on theoretical analysis and simulation experiment, this paper explored the performance of the system throughput rate, total time slot number and system recognition rate of the algorithm. Experimental results show that when the frame length of fs>2 and OVSF code length m>2, and the tag number is more than 200, the system throughput rate of OVSF-DFSA algorithm is m times that of DFSA algorithm, and compared with DFSA, MS-DFSA and PIGDFSA algorithm, OVSF-DFSA algorithm performs better in the above performances.
