A generalized multi-wavelength propagation model for VLC indoor channels using Monte Carlo simulation

Abstract

In this paper, we introduce the Matrix-MMC propagation model for indoor wireless optical channels. This proposed method is evolved from the modified Monte Carlo (MMC)-based ray tracing algorithm, but in addition to the properties of MMC, it has the capability of capturing reflection phenomena implying changes on wavelength (eg, fluorescence, phosphorescence, or iridescence) with a simplified analytical expression. The model provides unprecedented information about the mechanism of surface reflection in a visible light communication channel, which influences the propagation of the light waves, that depends on wavelength.
