N2 - Recently, there has been a growing interest in visible light communications (VLC) for indoor communication to meet the ever-increasing data demands. Most of the studies have considered the line-of-sight (LOS) channel for VLC communication. However, the LOS gain is constrained as the user moves away from the transmitter (Tx) or his device experiences orientation changes. It is observed in practice, the gain from reflections along the defused/NLOS channels can also contribute to optical gain. This research work, therefore, analytical model the NLOS channels and user’s device orientation and analyze its effect on the user’s SNR. For simulations, analytical models are integrated into ns3. Our results show that SNR slightly improves, which can be utilized to keep the communication alive during the high mobility scenario that could arise due to device orientation.
