“…These phenomena can incorrectly trigger the handover process. For this reason, the handover-based RSS resolves after a second dwell measure corroborates the failure [ 33 ]. In some scenarios, a fixed delay presents a poor performance in the handshake estimation.…”

Current vehicular systems require real-time information to keep drivers safer and more secure on the road. In addition to the radio frequency (RF) based communication technologies, Visible Light Communication (VLC) has emerged as a complementary way to enable wireless access in intelligent transportation systems (ITS) with a simple design and low-cost deployment. However, integrating VLC in vehicular networks poses some fundamental challenges. In particular, the limited coverage range of the VLC access points and the high speed of vehicles create time-limited links that the existing handover procedures of VLC networks can not be accomplished timely. Therefore, this paper addresses the problem of designing a vehicular VLC network that supports high mobility users. We first modify the traditional VLC network topology to increase uplink reliability. Then, a low-latency handover scheme is proposed to enable mobility in a VLC network. Furthermore, we validate the functionality of the proposed VLC network design method by using system-level simulations of a vehicular tunnel scenario. The analysis and the results show that the proposed method provides a steady connection, where the vehicular node is available more than 99% of the time regardless of the number of vehicular nodes on this network. Additionally, the system is able to achieve a Frame-Error-Rate (FER) performance lower than 10−3.

“…Thus, both the AP and the D2D transmitting IIoT share an equal Lambertian index (m k = m n ), m equals 1. Thus, expression (12) defines the geometry of a circle. The corresponding center, (x c , y c ) as well as the radius, R c is calculated as:…”

“…In these studies, they propose low-complexity heuristic algorithm and deep neural network for solving the problem. The studies reported in [10]- [12] suggest dynamic dynamic dwell timer and graph theory-based algorithms, tailored for D2D communication, in deciding whether or not it is beneficial for a user equipment to switch from VLC to RF or vice versa. Finally, [13] proposes a reinforcement learning (RL)-based approach to determine data transmission routes in an indoor VLC-D2D heterogeneous network.…”

“…At least, in [10], [11], it is said that this is initial work in this field, they do not consider the mobility of the users and they leave these aspects for further research. On the other hand, in [12], it is assigned a constant speed as v = 1 m/s. As a similar concept to the previous one, in [16], [17], the fixed distance between D2D devices is defined.…”

“…As a similar concept to the previous one, in [16], [17], the fixed distance between D2D devices is defined. However, it should be highlighted that, especially for [12], [16], [17], current studies are simulationbased results that cannot provide an analytical framework for backing up the simulations.…”

This paper analyses the performance of LiFi-based device-to-device (D2D) communication in industrial internetof-things (IIoT). We present a comprehensive analysis of mobility management of D2D communication in industrial LiFi networks. Using the semiangle at half illuminance of the AP and D2D transmitting IIoT, a coverage model for the D2D communication range is derived. By adopting stochastic geometry, closed-form expressions for mode selection rate and residence time are derived as functions of the AP density, IIoT density, and velocity. The results have shown that high velocity and denser deployment cause a decrease in the average D2D residence time and an increase in the average D2D transition rate or vice versa. The proposed analytical models are then verified with Monte Carlo simulation results. The results provide system-level design insights.
