Framed Slotted Aloha

A novel tag estimation algorithm named DFSA-MD1 is proposed, and applied to the field of tag identification that aims at decreasing tag collision number in RFID systems. The proposed algorithm regarded the tag identification process of a frame of the dynamic frame slotted ALOHA algorithm (DFSA) as an M/D/1 queuing system. The reader can estimate tag number of next frame from success slots number and collision slot number in current frame and current frame size according to M/D/1 queuing model.The experimental results show that DFSA-MD1 algorithm requires less time consumption and lower complexity for tag identificaiton and achieves the best performance of the DFSA tags identification protocols.

Simulation Results

RFID multi-tag identification process of the conflict on the basis of summing up the ALOHA class algorithm put forward an improved dynamic framed slotted ALOHA algorithm. Firstly, this paper uses the improved tag estimation algorithm to estimate the number of tags. Secondly, tag number is determined according to the length of the frame. Finally, tags are divided into several groups when the number of tags greater than the maximum frame length. The simulation results show that the efficiency of the algorithm has been improved obviously.
