Over the last decade, many models throughout the communication stack have been presented, which have increased the degree of realism that can be achieved with popular simulation frameworks. Nevertheless, the three-dimensional aspects of many real-world traffic situations barely find consideration. In this paper, we present a holistic approach to simulate large-scale three-dimensional VANET scenarios. We briefly summarize our previously presented models covering different aspects of communication in 3D scenarios, including an environmental diffraction model, an n-ray ground interference model, and the consideration of multi-floor communication. We then describe the principle of a model selector, which applies the appropriate models depending on the environment of the currently transmitted packet. Subsequently, we use the outlined methodology implemented in our Veins 3D framework to simulate a large urban reference scenario. The results differ significantly from comparable 2D simulations, demonstrating the necessity of three-dimensional considerations. However, they also show strongly increased execution times. Therefore, we further suggest different approaches to improve the simulation performance. Based on these optimizations, simulation durations in the same order of magnitude as a comparable 2D simulation can be achieved.}, language = {en} } @inproceedings{BrummerDeinleinDjanatliev2021, author = {Brummer, Alexander and Deinlein, Thomas and Djanatliev, Anatoli}, title = {On the Simulation of Vehicular Networking Scenarios in Multi-Story Parking Garages}, booktitle = {2021 IEEE Vehicular Networking Conference (VNC)}, editor = {Kargl, Frank and Altintas, Onur and Sommer, Christoph and Higuchi, Takamasa and Klingler, Florian}, publisher = {IEEE}, address = {Piscataway}, isbn = {978-1-6654-4450-7}, doi = {https://doi.org/10.1109/VNC52810.2021.9644620}, pages = {87 -- 94}, year = {2021}, language = {en} } @inproceedings{DeinleinBrummerGermanetal.2021, author = {Deinlein, Thomas and Brummer, Alexander and German, Reinhard and Djanatliev, Anatoli}, title = {On the Impact of Buildings on the LoS Evaluation in System-Level V2I/N Simulations}, booktitle = {2021 IEEE 94th Vehicular Technology Conference (VTC2021-Fall): Proceedings}, publisher = {IEEE}, address = {Piscataway}, isbn = {978-1-6654-1368-8}, doi = {https://doi.org/10.1109/VTC2021-Fall52928.2021.9625489}, year = {2021}, language = {en} } @inproceedings{BrummerGuetleinSchaeferetal.2021, author = {Brummer, Alexander and G{\"u}tlein, Moritz and Sch{\"a}fer, Matthias and German, Reinhard and Djanatliev, Anatoli}, title = {Experimental Evaluation of the N-Ray Ground Interference Model}, booktitle = {2020 IEEE Vehicular Networking Conference (VNC)}, publisher = {IEEE}, address = {Piscataway}, isbn = {978-1-7281-9221-5}, doi = {https://doi.org/10.1109/VNC51378.2020.9318362}, year = {2021}, language = {en} }
