| 摘 要： | 在RFID系统中，多标签引起的冲突一直是影响系统性能的问题。在分析ALOHA算法的基础上，提出一种分组动态帧时隙ALOHA算法。根据冲突情况，从数学角度对动态帧时隙ALOHA算法的标签数作出实时估计，动态地改变帧长或对标签进行分组来降低标签发生碰撞的概率，从而提高识别的效率。

| Abstract: | In the RFID system, the conflict caused by the multi-label has been affecting system performance. This paper proposed a grouping dynamic framed slotted ALOHA algorithm based on the analysis of ALOHA algorithm. According to the conflict situation, to make real-time estimates the number of tags on the dynamic framed slotted ALOHA algorithm from the mathematical point of view, Dynamically change the frame length or the labels are grouped to reduce the label probability of collisions, thereby improving the efficiency of the recognition. |
