在生产、制造和供应链管理领域，射频识别(RFID)被认为是最重要的技术之一。如今，移动RFID正越来越多地应用于仓库、超市、图书馆等工业领域的物品搜索和结账，它经常安装在手推车或叉车上。在使用移动RFID时，由于读写器不断移动，当他们试图读取标签时，它们可能会相互干扰。在这项研究中，我们提出了一种基于时分多址(TDMA)的移动RFID读写器防碰撞算法。该算法在阅读器发生冲突时，采用动态的帧大小调整策略，无需人工参数即可自动调整每个阅读器的帧大小。通过在移动RFID阅读器的模拟环境中进行的实验表明，与具有代表性的基于TDMA的防碰撞算法ColorWave相比，该方法的成功传输次数平均提高了228%。
In the fields of production, manufacturing and supply chain management, Radio Frequency Identification (RFID) is regarded as one of the most important technologies. Nowadays, Mobile RFID, which is often installed in carts or forklift trucks, is increasingly being applied to the search for and checkout of items in warehouses, supermarkets, libraries and other industrial fields. In using Mobile RFID, since the readers are continuously moving, they can interfere with each other when they attempt to read the tags. In this study, we suggest a Time Division Multiple Access (TDMA) based anti-collision algorithm for Mobile RFID readers. Our algorithm automatically adjusts the frame size of each reader without using manual parameters by adopting the dynamic frame size adjustment strategy when collisions occur at a reader. Through experiments on a simulated environment for Mobile RFID readers, we show that the proposed method improves the number of successful transmissions by about 228% on average, compared with Colorwave, a representative TDMA based anti-collision algorithm.
