摘要
在介绍动态帧时隙ALOHA算法的基础上,提出了一种帧长度调整算法。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,指导阅读器设定适当的值继续下一帧清点。仿真表明该方法具有可行性和实用性。
Based on an introduction of an anti-collision algorithm called dynamic framed slotted ALOHA,this paper proposes a new frame size adjusting method for the RFID system.The data of the successful slots number and the collision number in the current frame are used for predicting the number of the tags in the valid area of the reader.Thus the reader can use a more fitting frame size value to continue the inventory of the tag population in a new frame.The results of simulation demonstrate that this method is feasible and practical.
