Abstract:In the large-scale application of RFID, it is necessary for tag data processing to be moved to readers. Due to hardware conditions of readers, it is imperative to have an effective arithmetic for data processing and data structure to improve real-time process capability of readers. The paper analyzes data processing features of RFID readers and put forward a special T-linked tree. On the basis of T tree, there is a doubly linked list structure added, which enables readers to maintain high efficiency at each stage of data processing in read cycles. In addition to T-linked tree, the paper devises a set of arithmetic for data processing with a special data structure, which can enhance synchronous process ability of readers.
