Abstract :
Focus on the shortcoming of the most commonly used dynamic framed slotted ALOHA algorithm on the tag estimation and frame length in the RFID (Radio Frequency Identification) system, using the method of collision-count to record the times of collision and statistic the number of tags, which´s value of tag counter is equal with the times of identify cycle. Then use the grouping method for dynamic adjustment on the frame size of the reader in the identification process. The simulation results show that the enhanced program improve the throughput and identification of the RFID system efficiency.
