采用RFID技术查找畅销类产品

Finding Bestsellers Categories by Using RFID Technology

在基于有源电子标签构建的RFID系统中,如何以时间、能量有效的方式查找出畅销类产品是一个重要的研究问题。针对多阅读器RFID系统,首次对查找畅销类产品过程中的能量问题进行了研究,提出了一种基于分组机制的ETBC查找协议。该协议的核心思想是采用分组机制将同一属性产品上附着的标签分为一组,根据查找要求在相应组中找出样本标签,并基于样本标签回复的信息对其进行畅销类标签的查找。理论分析和仿真结果均表明了ETBC协议的有效性。相比针对全部标签进行查找的协议,ETBC协议的能耗要低很多,协议执行时间也大幅度减少。

In the RFID systems that constructed based on active tags, how to find the bestsellers categories in both time and energy efficient manner is an important research topic. Aiming at the multi-reader RFID system, for the first time, the energy issue in process of finding bestseller categories is researched, and the enhanced threshold-based classification （ETBC） finding protocol based on grouping mechanism is proposed. The core ideas of this protocol is using grouping mechanism, to make the tags adhered on same category products in a group, and in accordance with the finding requirement to find out the sample tag in corresponding group; and to find the bestsellers categories tags based on the reply messages from the sample tag. The theoretical analysis and simulation result all indicate the effectiveness of the ETBC protocol. Comparing with the finding protocol for all of the tags, ETBS protocol features lower power consumption, the execution time of protocol is also greatly reduced.
