| 摘 要： | 针对现有算法识别效率较低的问题, 提出一种基于等区域划分的射频识别（RFID）防碰撞算法. 通过对阅读器识别范围内的标签进行均等区域划分建立一种新型的分组结构, 并在每组中分别使用动态预测权值估计标签数目, 将其与最优时隙数调整方案相结合对标签进行识别, 解决了大规模标签应用场景中由于标签增多导致的系统稳定性差和吞吐率低的问题. 仿真结果表明, 该算法能有效提高系统吞吐率, 并减少通信过程中的时隙数.

| Abstract: | Aiming at the problem of low recognition efficiency of existing algorithms, we proposed a radio frequency identification (RFID) anti collision algorithm based on equal area division. Firstly, a novelgrouping structure was established by dividing the tags in the range of reader recognition into equal area. Secondly, dynamic prediction weights were used to estimate the number of tags in each group. Finally, it was combined with the optimal number of time slot adjustment scheme to identify the tags, which solved the problems of poor system stability and low throughput caused by the increase of tags in large scale tag application scenarios. Simulation results show that the algorithmcan effectively improve the throughput rate of system and reduce the number of time slots in the communication process. |
