  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. Vehicular Visible Light
Communication (VVLC) is preferred as a vehicle to everything (V2X)
communications scheme. Due to its highly secure, low complexity, and radio
frequency (RF) interference-free characteristics, exploiting the line of sight
(LoS) propagation of visible light and usage of already existing vehicle
light-emitting diodes (LEDs). This research is addressing the application of
the Non-Orthogonal Multiple Access (NOMA) technique in VLC based Vehicle-to-
Vehicle (V2V) communication. The proposed system is simulated in almost
realistic conditions and the performance of the system is analyzed under
different scenarios.
