Abstract：Dynamic Frame Slot ALOHA(DFSA) has been widely used to solve collision avoidance prob-lems in radio frequency identification(RFID) systems. In the DFSA algorithm,tag estimation and frame length adjustment are the key factors affecting the reader performance.In view of the above two points,an improved ALOHA algorithm for dynamic frame time slot is proposed.In the improved algorithm,the influ-ence of tag estimation error on the system is analyzed, and the mechanism of early adjustment of frame length is adopted.Experiments show that our improved algorithm not only reduces the system power con-sumption,but also improves the throughput of the system.
