摘　　要：针对RFID读写器识别多标签过程中出现的冲突问题,研究了基于EPC-C1G2协议的时隙随机算法,进行了时隙随机算法中Q值改变量计算以及碰撞标签时隙的调整。提出了一种改进的时隙随机Aloha算法。仿真结果显示,改进后的算法可增加系统吞吐率,提高了标签的识别速度。To solve the collision problem during the multi-label identification process in the RFID reader, a slot-random algorithm based on EPC CIG2 protocol is studied. We discuss the calculation of Q value variation and adjust the slot of the collision label, and then offer an improved slot-random algorithm. The simulation results show thai it can improve both the throughput of system and the speed of the label identification.
