Abstract
We investigate a novel approach of utilizing modern Adaptive Front-Lighting System (AFS) to reduce multiuser interference in Vehicular Visible Light Communications (V-VLC) by applying Space-Division Multiple Access (SDMA). V-VLC is a promising technology that can complement Radio Frequency (RF) communications to fulfill the high reliability and low latency requirements of Intelligent Transportation Systems (ITS). To achieve this, however, limitations of bandwidth efficiency and multiuser interference need to be addressed. A possible solution is to take advantage of SDMA, which allows spatial reuse of the resources and a simple but efficient multiple access method. State-of-the-art AFS, consisting of multiple controllable Light Emitting Diodes (LEDs) with sharply separated radiation patterns, offer a great opportunity to implement SDMA. Therefore, we investigate the applicability of an AFS-based SDMA system for V-VLC and compare its communication performance with a common LED-based high beam. Simulation results show that our system can be used to reduce multiuser interference in V-VLC.

We present a novel receiver-based interference reduction mechanism for Vehicular Visible Light Communication (V-VLC). V-VLC, in combination with Radio Frequency (RF)-communication, is a technology that is promising to enable a reliable communication link for a number of Intelligent Transportation Systems (ITS) applications such as cooperative driving. Both technologies complement each other to overcome technology-dependent limitations. Particularly, V-VLC is drawing attention as it is able to pr...

The C-V2X or LTE-V standard has been designed to support vehicle to everything (V2X) communications. The standard is an evolution of LTE, and it has been published by the 3GPP in Release 14. This new standard introduces the C-V2X or LTE-V Mode 4 that is specifically designed for V2V communications using the PC5 sidelink interface without any cellular infrastructure support. In Mode 4, vehicles autonomously select and manage their radio resources. Mode 4 is highly relevant since V2V safety applic...

We investigate the impact of various headlight modules and corresponding vehicle types on the performance of Vehicular VLC (V-VLC). V-VLC is currently considered as a quite promising communication technology that is complementary to existing wireless radio-based systems. Being a line of sight communication system, V-VLC is suggested mainly for shorter range communication causing little interference to concurrently performed transmissions. Given the very promising results in the literature, we st...

The ultimate goal of next-generation vehicle-toeverything (V2X) communication systems is enabling accident-free, cooperative automated driving that uses the available roadway efficiently. To achieve this goal, the communication system will need to enable a diverse set of use cases, each with a specific set of requirements. We discuss the main usecase categories, analyze their requirements, and compare them against the capabilities of currently available communication technologies. Based on the a...

Abstract Inter-vehicular connectivity to enhance road safety and support highly autonomous driving is increasingly becoming popular. Despite the prevalent works on radio-frequency (RF) based vehicular communication schemes, visible light communication (VLC) is considered to be a promising candidate for vehicular communications due to its low complexity and RF interference-free nature. Deployment of multiple light emitting diodes (LEDs) enables multiple-input multiple-output (MIMO) transmission i...

We argue on the need for a dedicated medium access control (MAC) for Vehicular VLC (V-VLC). The huge unlicensed spectrum that can support high throughput applications and the intrinsic security due to the LOS requirement make visible light a viable candidate for use in vehicular communications. In some first research work, the directionality of V-VLC has been considered and an initial conclusion was that the small collision domain leads to negligible interference and, thus, dedicated mechanisms ...

We investigate the impact of realistic light radiation pattern on Vehicular VLC (V-VLC) based on an empirical study for typical car headlight and taillight modules. Our research community identified visible light as a communication technology that has a number of advantages to radio communication. Besides the huge spectrum that is fully unlicensed, the technology allows for very high data rates and reduced interference from parallel communications. After seeing a number of breakthroughs in indoo...

In the context of an increasing interest toward reducing the number of traffic accidents and of associated victims, communication-based vehicle safety applications have emerged as one of the best solutions to enhance road safety. In this area, visible light communications (VLC) have a great potential for applications due to their relatively simple design for basic functioning, efficiency, and large geographical distribution.

Visible Light Communication (VLC) has recently been proposed as a low-cost and low-complexity technology for vehicular communications. In this paper, we propose the usage of dual channel VLC with the goal of providing enhanced vehicular connectivity to disseminate safety-critical messages and perform an experimental study to determine the spatial and angular limits of an off-the-shelf automotive Light Emitting Diode (LED) fog light. Single channel VLC refers to the independent transmission of di...

Platooning is one of the Intelligent Transportation System (ITS) applications that is envisioned to improve both road traffic safety as well as road capacity and environmental impact. The coordination of vehicles in a platoon depends on reliable real-time communication. In addition to Radio Frequency (RF)-based technologies such as Dedicated Short Range Communications (DSRC) and Cellular V2X (C-V2X), Line Of Sight (LOS) technologies such as Vehicular VLC (V-VLC) are considered to establish the n...

We investigate the influence of Non Line Of Sight (NLOS) components on the performance of Vehicular VLC (V-VLC). Given the steep rise of Intelligent Transportation Systems (ITS) for road safety applications, the need for reliable technologies for Vehicle-to-Vehicle (V2V) communication rises. Among others, V-VLC turned out to be a promising candidate to enhance vehicular connectivity, which nicely complements Radio Frequency (RF)-based technologies. V-VLC is supposed to be a Line Of Sight (LOS) c...
