N2 - This paper addresses the effects of blocking and shadowing due to peoples' movement on the performance of visible light positioning system based on received signal strength. We consider both line-of-sight and non-line-of-sight paths and using a non-sequential ray-tracing model, the channel is characterised with and without blocking and shadowing. A linear least square with a polynomial regression model is proposed for the position estimation. We show that, the VLP accuracy degrade by ~90 and ~67% due to blocking and shadowing, respectively. Besides, at a confidence interval of 90%, the positioning error ?p of 1.47 m is recorded with human blockage as compared with 0.15 m for the non-blocking cases while shadowing introduces ?p of 0.82 m compared with 0.27 m for the non-blocking case.
