In the context of the industrial Internet-of-things (IIoT), this study explores the performance evaluation of device-to-device (D2D) communication using light fidelity (LiFi). An extensive analysis of industrial LiFi networks' mobility management is provided. Based on the semi angle at half illuminance of the access point (AP) and D2D transmitting IIoT devices, a coverage model for the D2D communication range is generated. We provide closed-form formulas that use stochastic geometry to calculate the mode selection rate and residence time. These expressions are dependent on velocity, IIoT density, and AP density. According to our research, denser deployment and higher velocity cause the average D2D transition rate to rise and the average D2D residence duration to decrease, or vice versa. We use MATLAB simulations to evaluate the suggested analytical models, providing important information for system-level design. Device-to-device (D2D), LiFi, optical wireless communication, visible light communication, Industrial Internet-of-Things (IIoT), and other concepts are important to understand.
