Handover Modelling for Indoor Li-Fi Cellular Networks: The Effects of Receiver Mobility and Rotation

Abstract: Light-fidelity (Li-Fi) is an emerging technology for wireless networking based on
visible light communication (VLC). Optical attocells are smaller in size than the radio
frequency (RF) femtocells. A fundamental approach is proposed for handover modelling by
taking into account the effects of both mobility and rotation for a connected user equipment
(UE). By using a random waypoint (RWP) model for the receiver movement and a geometric
model for the receiver orientation, the probability of handover and the handover rate are
calculated. Novel insights are provided into the handover performance in indoor optical
attocell networks using Monte Carlo simulations.
