Light-fidelity (LiFi) is a fully-networked bidirectional optical wireless communication (OWC)
technology that is considered as a promising solution for high-speed indoor connectivity …

Among the challenges of realizing the full potential of light-fidelity (LiFi) cellular networks are
user mobility, random device orientation, and blockage. In this paper, we study the impact of …

In this paper, we investigate the dynamic power allocation for a visible light communication
(VLC) cellular system consisting of two coordinating attocells, each equipped with one …

Link instability induced by users' mobility is one of the challenges of optical wireless
communications (OWC) inherited from the propagation nature of light. Hence, good …

Visible light communication (VLC) is a key enabler for high-speed indoor connectivity and
