文章阐述了无线射频识别(RFID)系统以及RFID中间件的功能, 提出一种二叉树数据过滤算法, 将应用于中间件的数据过滤功能前移到读写器。通过与中间件的数据过滤方法进行比较, 得出了二叉树数据过滤方法更优的结论, 最后给出了RFID中间件未来的发展趋势。

This article elaborates the RFID system and the functions of RFID middleware, then proposes a binary tree data filtering algorithm, moves the data filtering function applied in the middleware forward to the reader, thus concluding that in comparison with the data filtering algorithm, this algorithm is even better. Finally it predicts the prospect of the development of RFID middleware.
