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

Abstract

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 userspecific
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.
