  VLC is attracting a lot of attention as an emerging potential technology for
deployment in next generation indoor wireless networks. Use of efficient link
switching scheme among VLC access points is critical in indoor environment to
provide seamless connectivity to mobile users. This paper presents a novel
position prediction link switching scheme for indoor visible light
communication systems. The method exploits the fact that indoor scenario (light
fixtures/furniture) mostly remains unchanged, therefore, this information can
be stored at the coordinator end. Thus, the user is not required to search for
the best transmitter when RSS is reduced to a threshold value as in
conventional methods which cause substantial delay in switching process.
Simulation results show that the proposed scheme for indoor VLC System achieves
the dual purpose of adequate illumination and mobility to user in considered
indoor scenario.
