摘　　要：为高效保障可见光通信(VLC)和无线射频(RF)通信异构网络服务质量(QoS),研究设计了基于统计时延QoS保障的网络资源匹配算法,旨在提高网络服务资源利用率。将切换服务过程和随机到达过程构建成网络队列系统,采用有效带宽与有效容量理论进行分析。评估了当VLC网络受遮挡中断时,需要RF网络提供的最小服务速率。利用Matlab对算法进行仿真,分析了系统参数改变对算法的影响。算法可以为异构网络的QoS保障及资源分配研究提供一定的指导。To effectively guarantee the quality of service(QoS)in heterogeneous Visible Light Communication(VLC)and Radio Frequency(RF)Communication networks,we have designed a network resource matching algorithm based on the guarantee of statistical delay,which aims to improve the utilization of network service resources.We constructed a network queuing system with the switching service process and random arrival process,and the effective bandwidth and effective capacity theory was used for the analysis.The minimum service rate provided by RF was evaluated when the VLC network was interrupted by occlusion.The algorithm was simulated by Matlab,and the influence of the variable system parameter on this algorithm was analyzed.The algorithm could provide some guidance for the research of QoS guarantee and resource allocation in heterogeneous networks.
