Abstract

Vehicular Visible Light Communication (V-VLC) has recently emerged as a promising technology for vehicular networking. This technology is based on the concept of using LEDs in modern cars’ lighting modules for communication while preserving their illumination functionality. V-VLC has certain characteristics that can complement well RF technologies. The Line Of Sight (LOS) characteristics of VLC, the directionality of the light waves, and the confined collision domain can substantially reduce interference and improve resilience against security attacks on communication. Therefore, combining radio communications with V-VLC can provide reliable communication, as required by various vehicular networking applications. As a new technology, however, V-VLC requires further fundamental research, e.g., on the impact of automotive lighting modules on communication, multi-user interference, and medium access. To that end, in the first part of this thesis, we focus on understanding the characteristics of head- and taillights as V-VLC transmitters. We develop empirical modeling methodologies and describe the validation process based on real-world measurements. Then, we show that the V-VLC link stability is greatly impacted by the road geometry (straight and curved roads) and the cars’ arrangement thereon. Additionally, we show that differences in headlights based on vehicle type, model, and lighting function (low beam or high beam) impact communication, despite adhering to the same illumination standards. In the second part of this thesis, we study medium access and address the problem of multi-user interference in V-VLC. We characterize V-VLC interference in a large-scale urban scenario and show that despite the directionality of VLC, multi-user interference presents a challenge in certain situations. To address this challenge, we design a medium access protocol that uses lighting modules as sector antennas. Using the vehicles’ positions and beamforming for transmission, we are able to effectively reduce interference. We improve communication by halving the ratio of collisions and increasing the packet delivery ratio.
