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 modelsenChannel modelsVisible Light CommunicationsOptical Wireless CommunicationsLight Emitting DiodeChannel impulse responseArticle
