光保真度（LiFi）接入点（ap）可以部署在任何地方，以支持各种轻量级手持和智能物联网（IoT）设备和应用的指数级增长。物联网流量通常是零星的，由异构突发流组成，这可能会影响所支持的无线服务的性能。本文提出了一种基于最佳数据速率的切片方案，根据用户的数据速率需求和业务需求，动态虚拟化网络LiFi AP下行信道带宽。我们制定了一个游戏优化问题，该问题捕获了三个主要实体之间的关系：LiFi蜂窝网络基础设施提供商（InP），移动虚拟网络运营商（MVNOs）和物联网或无线用户。软件定义网络（SDN）控制器使InP能够根据mvno的服务水平协议（sla）和物联网服务的流量概况，将LiFi AP下行通道切片重新配置到mvno。仿真结果表明，所提出的AP资源切片方案在物联网应用中具有良好的应用前景。
Light-Fidelity (LiFi) access points (APs) can be deployed anywhere to support the exponential growth of various lightweight hand-held and smart internet-of-things (IoT) devices and applications. IoT traffic is often sporadic and consists of heterogeneous bursty flows, which may affect the performance of supported wireless services. This paper develops an optimal data rate-based slicing scheme that dynamically virtualizes a networked LiFi AP downlink channel bandwidth according to the data rate demands of users and the requested services. We formulate a game optimization problem that captures the relation between three main entities: a LiFi attocellular network infrastructure provider (InP), mobile virtual network operators (MVNOs), and IoT or wireless users. A software-defined networking (SDN) controller enables the InP to reconfigure the LiFi AP downlink channel slices to MVNOs, based on their service-level agreements (SLAs) and the traffic profile of IoT services. Simulation results show that the proposed AP resources slicing scheme is promising for IoT applications.
