Abstract

Abstract: Based on framed slot ALOHA protocol，the anti-collision algorithm（Q algorithm） of ISO18000-6 Type C is improved.At the end of frame，improved Q algorithm updates Q by means of a detection mechanism.Because the length of frame in every round of improved Q algorithm automatically adaptes the better value，improved Q algorithm reduces the number of slots and rounds of identification.Simulation results show that improved Q algorithm is more efficient than the Q algorithm of Type C protocol.

Key words: Radio Frequency Identification（RFID）, frame-ALOHA, anti-collision

摘要： 基于帧时隙ALOHA协议，对ISO18000-6 Type C标准中采用的防冲突算法（Q算法）进行改进。在帧的结束处，改进的Q算法通过检测机制来进行Q值的更新。因为改进的Q算法中每个清点周期的帧大小都会自动地取较优值，所以降低了识别所需要的总时隙数和周期数。仿真结果显示改进的Q算法比Type C标准中的Q算法更有效。
