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。

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 .
