The incorporation of VLC in vehicular scenarios has been studied for several years. This technology is also recognized as a green technology that does not interfere with radio-frequency-based communications. The reception can be possible using photodiode-based receivers or even image sensors. It modulates optical signals by adjusting the power at high-frequency intervals to be undetected by the human’s eyes. VLC enables data transmission in the visible light spectrum (from 380 nm to 780 nm) using solid-state lighting. Visible Light Communication (VLC) is a potential alternative, which can take advantage of the existing street lighting infrastructure and vehicle lamps to reduce implementation and operation costs.

Other technologies have emerged to support service under adversary conditions for DSRC.

Moreover, it can receive a safety message to prevent collisions or any other possible risk. It ensures that the vehicle does not have any issue and that it can be located in case of an emergency. Using DSRC, the vehicle reports its status and position continuously at a minimum frequency of 10 Hz. This active vehicle-based safety system has been tested, standardized, and approved by the United States Department of Transportation (USDOT) and some principal car manufacturers such as Toyota, Ford, GM, etc. Vehicle Safety Communications (VSC) has defined safety applications to work under the Dedicated Short Range Communication (DSRC) technology. As a consequence of this demand, several communication technologies have been developed. With the connected vehicle market becoming the standard for new cars, they will require the capability to receive real-time information from other vehicles and the roadside infrastructure provided by local authorities. In the specific case of the vehicular industry, we expect that Internet-connected vehicles will enable safer driving and enhance passenger experiences. In the last decade, the use of the Internet has improved, simplified, and brought new services to many sectors of the economy. Additionally, the system is able to achieve a Frame-Error-Rate (FER) performance lower than 10 −3. 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. Furthermore, we validate the functionality of the proposed VLC network design method by using system-level simulations of a vehicular tunnel scenario. Then, a low-latency handover scheme is proposed to enable mobility in a VLC network. We first modify the traditional VLC network topology to increase uplink reliability. Therefore, this paper addresses the problem of designing a vehicular VLC network that supports high mobility users. 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. However, integrating VLC in vehicular networks poses some fundamental challenges. 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.
