    Vehicular visible light communications: The impact of taillight radiation pattern
    (IEEE, 2020-09) Eldeeb, Hossıen Badr; Eso, E.; Uysal, Murat; Ghassemlooy, Z.; Zvanovec, S.; Sathian, J.; Electrical & Electronics Engineering; UYSAL, Murat; ELDEEB, Hossien Badr Hossien
    We investigate the path-loss of vehicular visible light communications based on the radiation pattern of a commercial car taillight. The measured pattern is incorporated into a ray-tracing model and simulation results indicate up to 4.2 dB variation in the path-loss compared with the Lambertian model.

    Vehicular VLC: A ray tracing study based on measured radiation patterns of commercial taillights
    (IEEE, 2021-08-15) Eldeeb, Hossıen Badr; Eso, E.; Jarchlo, E. A.; Zvanovec, S.; Zvanovec, S.; Uysal, Murat; Ghassemlooy, Z.; Sathian, J.; Electrical & Electronics Engineering; ELDEEB, Hossien Badr Hossien; UYSAL, Murat
    In this letter, we investigate the performance of vehicular visible light communications based on the radiation patterns of different commercial taillights (TLs) using non-sequential ray tracing simulations. Our simulation results indicate a significant variation in the path loss compared with Lambertian model. Based on the ray tracing results, we propose a new path loss model as a function of the propagation distance considering the asymmetrical radiation pattern of TLs. We use this model to derive the attainable transmission distance. We further present the delay spread for various vehicular communication scenarios to demonstrate the effect of neighboring vehicles.
