“…Note that VLC is fundamentally based on the line-of-sight (LOS) communication. There is an increased chances of connectivity loss for VLC based vehicular network [14]. In order to address these issues, researchers have proposed hybrid RF/VLC systems [15]- [18], where end users can benefit the wide coverage area provided by RF systems and the large data rates from VLC systems.…”

Visible light communication (VLC) has recently emerged as an affordable and scalable technology supporting very high data rates for short range vehicle-to-vehicle (V2V) communication. In this work, we advocate the use of vehicular-VLC (V-VLC) for basic safety messages (BSMs) dissemination in lieu of conventional vehicular radio frequency (V-RF) communication in road intersection applications, where the reception performance is affected by interference from the concurrent transmissions of other vehicles. We make use of stochastic geometry to characterize the interference from the same lane as well as the perpendicular lane for various network configurations, i.e., standalone V-VLC, stand-alone V-RF and hybrid V-VLC/V-RF network. Specifically, by modelling the interfering vehicles' locations as a spatial Poisson point process (PPP), we are able to capture a static two-dimensional road geometry as well as the impact of interference due to vehicles clustering in the vicinity of road intersection in terms of outage probability and throughput. In addition to above, the performance of spatial ALOHA and carrier sense multiple access with collision avoidance medium access control (CSMA/CA MAC) protocol for standalone V-VLC, standalone V-RF and hybrid V-VLC/V-RF network configuration for relaying BSMs at road intersection is also compared. The performance metrics such as delay outage rate (DOR) and information outage rate (IOR) are utilized to investigate the impact of latency associated with various network configurations. Our numerical results reveal that our proposed hybrid V-VLC/V-RF leads to significant improvement in terms of outage performance, throughput and latency as compared to stand-alone V-VLC or stand-alone V-RF network.

“…Since the sensing and communication technologies gather more information to improve the controller efficiency, the user preferences must be met in order to improve the safety and comfort of CAV systems. Bugra Turan and Seyhan Ucar [7] described in their work of "Vehicular Visible Light Communications" that the purpose of intelligent transportation systems with vehicular communication is to reduce congestion, accident, energy and time wastage. But vehicular communications are assumed to provide efficiency regarding of those problems.…”

IntroductionVehicular Ad-hoc Networks (VANETs) are created by applying the principles of Mobile Ad-hoc Networks (the spontaneous creation of a wireless network of mobile devices) to the domain of vehicles. VANET is a technology that uses moving vehicles as nodes for creating mobile networks. VANET can create a wide range of networks by changing every vehicle into a wireless node and allowing cars to connect to each other that are 100-300 metres apart. VANETs were first mentioned and introduced in 2001 under "car-to-car ad-hoc mobile communication and networking" applications, where networks can be formed and information can be relayed among cars. It was shown that vehicle-to-vehicle and vehicle-to-roadside communications architectures will co-exist in VANETs to

“…Visible light communication (VLC) systems utilize existing LED head/tail lights and low-cost photodiodes for line-ofsight (LoS) communication and are therefore more secure and less susceptible to interference and multipath effects in congested settings. VLC is expected to complement the robust V2V communication architecture of future AVs [3].…”

Vehicle-to-vehicle (V2V) communication and positioning systems are expected to play an important role in the development of future automated and autonomous vehicle safety concepts. Visible light communication and positioning (VLC and VLP) promise high data rates and cm-level positioning accuracy, respectively, with vehicle head/tail lights. Existing methods for vehicular VLP often require multiple spatially-separated co-operating nodes with either tightly synchronized clocks or precisely known relative locations and they dictate certain modulation schemes or message content for the VLC subsystem. The proposed novel VLP method utilizes a single VLC receiver capable of measuring angle-of-arrival (AoA) on a receiving vehicle (RXV). The method dictates no modulation constraints on the VLC subsystem and no cooperation is required from the transmitting vehicle (TXV) other than disseminating its real-time speed and heading information via VLC. The method uses speed and heading data and two consecutive AoA samples from the same receiver to deduce 2D position of the TXV relative to the RXV with triangulation. Simulation results show the method performs cm-level positioning accuracy at >50Hz rates under realistic road and VLC channel conditions. With such performance, the proposed VLP method enables time-critical traffic safety applications like collision avoidance.
