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0.005～0.01 ms之间,具有良好的性能.
Abstract
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 pri-ority,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.
