Indoor Visible Light Communication Scheduling for IOT Scenarios with Short Blocklength

We consider visible light communication (VLC) for Industrial Internet of Things (IOT), where multi-user area aggregation and distributed scheduling are adopted to improve network throughput and reduce user packet loss rate. For one thing, because of the massive connection, it faces huge computational complexity, and for another, when allocating limited resources, it is also necessary to consider the quality of service requirements. Based on the above requirements, we have proposed an approach of user area aggregation and maximizing the user sum throughput. In addition, we consider short packet transmission as the control message in Industry 4.0, and derive the achievable transmission rate of short packet. To solve the optimization problem, we adopt the Markov decision process (MDP). Simulation results show the performance gain over the conventional Round-robin method.
