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.

“…In [12], the use of control tone signals for managing the handover in indoor VLC systems was considered, which offered a solution for determining the AP information with the user's mobility. For vehicular VLC networks, frequency diversity-based handover solutions and low-latency handover schemes were proposed in [13] and [14], respectively, while soft handover solutions were proposed in [15]- [17], yet, without focusing on the efficiency of resource utilization. In particular, in [15], hard handover and coordinated multipoint transmission (CoMP) decisions were proposed based on received signal strength but the effect of handover delay and the efficiency of resource utilization were not investigated.…”

“…The demand for location-assisted mobile data communication for indoor networks is increasing. According to information shared by [1]- [3], it is expected that communications data traffic will reach approximately 77 exabytes per month in the coming years, where 70% to 90% of global data traffic will occur indoor environments. The widespread use of light-emitting diodes (LEDs) for interior lighting has been an opportunity to create a whole new form of internal communication and indoor positioning system [4]- [6].…”

The widespread deployment of white light-emittingdiodes (LEDs) for illumination provides a unique opportunity to create a flexible, accurate, and ubiquitous indoor communication and positioning system. Recent studies have shown that determining the position of a person or an object in a room can use the signals transmitted by LEDs. In this paper, we exploit the location information obtained via LEDs to improve the communication performance of an indoor visible light communication (VLC) system. Specifically, we propose an optimal LED power management framework to maximize the average data rate across the room while satisfying the bit error rate (BER) and illumination constraint across the room. The maximum allowed localization error, as a function of the number of blockages and the LED irradiance angle, have been calculated. In addition, the closed-form expression for the BER is derived for the proposed optimal LED power allocation scheme. We have also formulated an optimization problem that will maximize the power savings among the LEDs with respect to the number of blockages and permissible error in localization. It has been shown that, by employing the proposed optimal LED power allocation will results in a significant amount of power-saving, which is approximately 40% for 4 LEDs configuration and 70% for 8 LEDs configuration as compared to equal power allocation. Further, the maximum allowed localization error is found out to be approximately 7 cm and 18 cm with 4 and 8 LEDs, respectively, to achieve the maximum achievable data rate. Finally, it is shown that the dimming range of up to 70% can be achieved for the proposed system.
