The Simulation Research of Dynamic Anti-collision

In this paper, we evaluate the performance of anti-collision algorithm of RFID system. We research dynamic framed slotted algorithm (DFSA) based on EPC Gen2 protocol based on this we studied a kind of framed time slot improvement algorithm (EDFSA) this algorithm absorb the merit of dynamic framed time slot algorithm , this algorithm solve the problem. When huge number of label quantity need to be identified the system efficiency will reduced. Through the simulation experiment we compared the advantage and disadvantage of EDFSA, BFSA and DFSA three algorithm performances and then we draw the following conclusion. When identify 1000 tags time cost of EDFSA algorithms changes 85%, 92% separately compare the BFSA algorithm and the DFSA algorithm ,and when identify more tags EDFSA will obtain a better performance.
