Human Body Impact on Mobile Visible Light Communication Link

Shadowing impact for indoor mobile visible light communications (VLC), is linked to the person wearing the optical receiver, depending on the body features and varying according the data rate. Here, we investigate VLC performance considering two body models with different reflectivity values. In addition, we consider a mobile receiver with random orientations to account body movements. Results show that for low data rates, a 2D body model with perpendicular receiver orientation allows suitable performance estimation. For high data rates, 2D body model can be used but link efficiency is deteriorated depending on receiver orientation variations whatever body reflectivity values are.
