摘要

提出了一种用于EPC第1类第2代(C1G2)协议的基于动态帧开槽Aloha (DFSA)的改进q算法。在该算法中，通过计算q值调整的最优阈值，减少了识别过程中的帧总数和QueryAdjust命令的不必要发送，并利用带有碰撞处理阈值(CPT)策略的二值选择(BS)和预测比特(PB)分别提高了识别效率和速度。仿真结果表明，改进后的q -算法占用的时隙更少，系统吞吐量在47%左右波动，比EPC C1G2提高至少20%。

An improved Q-algorithm based on EPC Class 1 Generation 2 protocol

In this paper, an improved Q-algorithm based on Dynamic Framed Slotted Aloha (DFSA) used in EPC Class 1 Generation 2 (C1G2) protocol is proposed. In the proposed anti-collision algorithm, the total number of frames and the unnecessary sending of QueryAdjust commands are reduced in the recognition process by calculating the optimal threshold for adjusting Q. Besides, the identification efficiency and speed are improved by utilizing the Binary Selection (BS) with Collision Processing Threshold (CPT) strategy and Prediction Bit (PB), respectively. Simulation results show that the improved Q-algorithm costs less time slots and the system throughput fluctuates around 47% which is at least 20% higher than EPC C1G2.
