Cell-Centric and User-Centric Multi-User Scheduling in Visible Light Communication aided networks

Visible Light Communication (VLC) combined with advanced illumination has been expected to become an integral part of next generation heterogeneous networks at the time of writing, by inspiring further research interests. From both the Cell-Centric (CC) and the User-Centric (UC) perspectives, various VLC cell formations, ranging from fixed-shape regular cells with different Frequency Reuse (FR) patterns and merged cells employing advanced transmission scheme to amorphous user-specific cells are investigated. Furthermore, different Multi-User Scheduling (MUS) algorithms achieving Proportional Fairness (PF) are implemented according to different cell formations. By analysing some critical and unique characteristics of VLC, our simulation results demonstrate that, the proposed MUS algorithms are capable of providing a high aggregate throughput and achieving modest fairness with low complexity in most of the scenarios considered.
