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...
In this paper we study the impact of both receiver orientation and position on Visible Light Communication (VLC) performance when it is worn by a moving person in indoor environment. This is the case for example of a tablet or smartphone. Because of person mobility within the environment, there are cases where Line of Sight (LOS) paths from optical light sources at the ceiling cannot be collected...
This paper presents a new optimized simulation algorithm of the optical wireless channel. It has a faster convergence for SISO (Single Input Single Output) systems, while it significantly reduces computation time for MISO (Multiple Inputs Single Output) systems, which are the main ones in WBANs (Wireless Body Area Networks). Our algorithm is based on Monte Carlo methods, and uses 3D launched rays...
