Abstract

Abstract

Focusing on the difficulty of jointly optimizing lighting and throughput in indoor cell-free Visible Light Communication (VLC) network, a method of VLC Cooperative User Access and Dynamic Power Adjustment (VCUA-DPA) is proposed. In the user access stage, by considering the network load balance, user rate demands and the limitation of the number of cooperative cells, a user access algorithm through user and VLC cooperating is designed in this paper. In the power allocation stage, a dynamic power adjustment algorithm is designed to optimize jointly illumination uniformity and system throughput. Simulation results show that the proposed VCUA-DPA can significantly improve the system throughput and optimize the indoor illumination uniformity.
