Abstract

Abstract: Visible Light Communication (VLC) is a subset of Optical Wireless Communication (OWC) originally based on Light Emitting Diodes (LEDs) for data transmission in an imperceptible way to human vision. Thanks to its wide license-free bandwidth, high security, and its low cost, VLC becomes a revolutionary alternative to the Radio Frequency (RF) networks. This paper presents a comprehensive survey of VLC channel modeling techniques. It describes the main VLC channel components. It gives different channel models in indoor, outdoor, underwater, and underground environments. It draws a synthesis comparing the algorithms proposed in each environment. Moreover, the paper gives concluding remarks and future research directions for VLC channel models. Highlights: An Overview on VLC channel models: definition, architecture, and methods. Classification of VLC channel models according to four environments (indoor, outdoor, underwater, and underground). Synthesis and discussions including the most used approaches for each environment and the most evaluated metrics.
