摘要
文中提出了一种帧长度调整算法,针对于RFID系统中,使用了帧时隙ALOHA算法作为防碰撞方案的情况。该方法利用一帧周期中碰撞及正确接收的信息推测阅读器有效范围内可能存在的标签数目,从而指导阅读器设定适当的值继续下一帧清点。通过仿真,表明该方法可应用于实际的帧时隙ALOHA算法中,辅助实现多标签的清点,该算法容易实现,且可满足对标签信息的实时处理。
In this paper,A new framesize adjusting method is proposed for the RFID system which make use of Frame Slotted ALOHA algorithm as its anti-collision plan. The data of the successful slots number and the collision number in the current frame is used for predicting the number of the tags in the valid area of the reader.Thus the reader can use a more fitting framesize value to continue the inventory of the tag population in a new frame.The results of simulation demonstrate that this method can be applied in the frame slotted ALOHA algorithm,assisting the inventory of the tag population.It can be easily carried out and satisfy the real-time processing of the tags＂ information.
