摘　　要：将轮询算法(RR)和比例公平算法(PF)相结合,提出了一种改进的轮询(IRR)算法.算法将用户请求速率和时延两者加权作为用户优先级,对时延较大的用户做出优先级补偿.仿真结果表明,在VLC/WiFi异构网络中,IRR算法提高了带宽分配的公平性,公平性指数在0.98以上,用户平均时延保持在0.005~0.01ms之间,具有良好的性能.An improved Round-Robin(IRR)algorithm is proposed by combining Round-Robin(RR)and Proportional Fairness(PF).The algorithm weights the user request rate and delay as the user priority,and makes priority compensation for users with larger delay.The simulation results show that the IRR algorithm has good performance by improving the fairness of the VLC/WiFi heterogeneous network,with the fairness index above 0.98 and average delay between 0.005-0.01 ms.
