摘要：

Dynamic ALOHA-algorithm is an anti-collision algorithm highly concerned in RFID system. After we analyzed the existing ALOHA-algorithm, a new dynamic frame slotted ALOHA-algorithm was proposed, which can dynamically change frame length through the feedback of the last collision slot number in one inventory frame. The simulation indicates that this algorithm has nearly the same performance evaluation on system efficiency and less total number slots required identifying tags, compared to the estimating real-time tag quantity near the readers. Especially this algorithm is simple for RFID system application and keeps compromise between efficiency and complexity.
