摘　　要：中间件技术作为射频识别(RFID)应用中的一项重要技术,逐渐成为国内外研究的热点。本文从应用角度出发,提出了一种基于动态时间窗的RFID中间件数据过滤算法,并仿真比较了经过动态时间窗和固定时间窗过滤后的数据冗余度。仿真结果表明,基于动态时间窗的数据过滤算法可以较好地提高RFID中间件中传输数据的有效性。Radio Frequency Identification（RFID） middleware, as an important technique of RFID, has become a central concern. From the application point of view, a RFID middleware data filtering algorithm based on dynamic time window is proposed. Simulation comparing tests are carried out between the data redundancy transmitted in the RFID middleware based on dynamic time window and that based on fixed time window. The simulation results show that the data filtering algorithm based on dynamic time window can improve the validity of data transmitted in the RFID middleware preferably.
