摘要
针对可见光通信(Visible Light Communication,VLC)系统,为实现网络服务质量(Quality of Service,QoS)的高效保障,提高带宽资源利用率,本文研究了时延QoS约束下的资源预留算法。研究建模分析了具有多包接收(Multi-packet Reception,MPR)能力的Aloha服务,计算了服务过程的有效容量。用泊松(Poisson)过程描述业务到达,评估了Poisson到达下的带宽需求。通过搜索算法,求解了保障QoS需要预留的服务资源,利用Matlab对算法进行了仿真实现及分析。
Aiming at Visible Light Communication(VLC)system,in order to realize the efficient guarantee of network of Quality of Service(QoS),and improve the utilization rate of bandwidth resource,this paper studies a algorithm of resource reservation under delay QoS constraint.The Aloha service with Multi-packet Reception(MPR)capability is modeled and analyzed,and the eff ective capacity of the service process is calculated.Poisson process is used to describe the service arrival,and the bandwidth requirement under Poisson arrival is evaluated.Through the search algorithm,the reserved service resource needed to guarantee QoS is solved.The algorithm is simulated and analyzed by Matlab.
