摘要

射频识别（RFID）系统中

存在多个电子标签同时响应读写器的可能性

这将使得电子标签产生碰撞现象。在对帧时隙ALOHA算法分析的基础上

提出了一种改进的RFID动态帧时隙ALOHA算法。该算法通过对读写器范围内的标签数进行估计

设置最佳帧长度

使RFID系统获得最大吞吐量

从而提高标签的识别效率。仿真结果表明:与传统ALOHA算法相比

性能有明显改善。

Abstract

In radio frequency identification（RFID） system

there is one possibility that many electronic tags response one reader at the same time

which will cause electronic tag collision.An enhanced dynamic frame slotted ALOHA algorithm for anti-collision in RFID systems is proposed by analyzing frame slotted ALOHA algorithm. This algorithm makes the RFID system get the maximum throughput and improve the tags recognition efficiency by estimating the tag number within the scope of the reader and setting the best frame length.Simulation results show that the property of the proposed algorithm is improved

compared with traditional ALOHA algorithm.
