Promising Parallel Discrete Event Simulation (PDES) approaches with optimistic and conservative synchronisation schemes have emerged throughout the years. However, in the area of real-time simulation, PDESs are rarely considered. This is caused by the complex problem of fitting parallel executed DES models to a real-time clock. Hence, this paper gives an extensive review of existing conservative and optimistic synchronisation schemes for PDESs. It introduces a metric to compare their real-time capabilities to determine whether they can be used for soft or firm real-time simulation. Examples are given on how to apply this metric to evaluate PDESs using synthetic and real-world examples. The results of the investigation reveal that no final answer can be given if PDESs can be used for soft or firm real-time simulation as they are. However, boundary conditions were defined, which allow a use-case specific evaluation of the real-time capabilities of a certain parallel executed DES. Using this in-depth knowledge and can lead to predictability of the real-time behaviour of a simulation run.}, language = {en} } @inproceedings{RieblObermaierNeumeieretal.2017, author = {Riebl, Raphael and Obermaier, Christina and Neumeier, Stefan and Facchi, Christian}, title = {Vanetza: Boosting Research on Inter-Vehicle Communication}, booktitle = {Proceedings of the 5th GI/ITG KuVS Fachgespr{\"a}ch Inter-Vehicle Communication (FG-IVC 2017)}, editor = {Djanatliev, Anatoli and Hielscher, Kai-Steffen and Sommer, Christoph and Eckhoff, David and German, Reinhard}, publisher = {Friedrich-Alexander Universit{\"a}t Erlangen-N{\"u}rnberg}, address = {Erlangen}, url = {https://nbn-resolving.org/urn:nbn:de:bvb:29-opus4-85280}, pages = {37 -- 40}, year = {2017}, language = {en} } @inproceedings{NeumeierObermaierFacchi2017, author = {Neumeier, Stefan and Obermaier, Christina and Facchi, Christian}, title = {Speeding up OMNeT++ Simulations by Parallel Output-Vector Implementations}, booktitle = {Proceedings of the 5th GI/ITG KuVS Fachgespr{\"a}ch Inter-Vehicle Communication (FG-IVC 2017)}, editor = {Djanatliev, Anatoli and Hielscher, Kai-Steffen and Sommer, Christoph and Eckhoff, David and German, Reinhard}, publisher = {Friedrich-Alexander Universit{\"a}t Erlangen-N{\"u}rnberg}, address = {Erlangen}, url = {https://nbn-resolving.org/urn:nbn:de:bvb:29-opus4-85280}, pages = {22 -- 25}, year = {2017}, language = {en} } @inproceedings{ObermaierRieblFacchi2018, author = {Obermaier, Christina and Riebl, Raphael and Facchi, Christian}, title = {Fully Reactive Hardware-in-the-Loop Simulation for VANET Devices}, booktitle = {2018 IEEE Intelligent Transportation Systems Conference}, publisher = {IEEE}, address = {Piscataway}, isbn = {978-1-7281-0323-5}, doi = {https://doi.org/10.1109/ITSC.2018.8569663}, pages = {3755 -- 3760}, year = {2018}, language = {en} } @inproceedings{ObermaierRieblFacchi2017, author = {Obermaier, Christina and Riebl, Raphael and Facchi, Christian}, title = {Dynamic scenario control for VANET simulations}, booktitle = {5th IEEE International Conference on Models and Technologies for Intelligent Transportation Systems: Proceedings}, publisher = {IEEE}, address = {Piscataway}, isbn = {978-1-5090-6484-7}, doi = {https://doi.org/10.1109/MTITS.2017.8005599}, pages = {681 -- 686}, year = {2017}, language = {en} } @inproceedings{ObermaierFacchi2017, author = {Obermaier, Christina and Facchi, Christian}, title = {Observations on OMNeT++ Real-Time Behaviour}, booktitle = {Proceedings of the 4th OMNeT++ Community Summit}, publisher = {arXiv}, address = {Ithaca}, doi = {https://doi.org/10.48550/arXiv.1709.02207}, year = {2017}, language = {en} } @inproceedings{ObermaierRieblFacchietal.2021, author = {Obermaier, Christina and Riebl, Raphael and Facchi, Christian and Al-Bayatti, Ali H. and Khan, Sarmadullah}, title = {COSIDIA: an approach for real-time parallel discrete event simulations tailored for wireless networks}, booktitle = {SIGSIM-PADS '21: Proceedings of the 2021 ACM SIGSIM Conference on Principles of Advanced Discrete Simulation}, publisher = {ACM}, address = {New York}, isbn = {978-1-4503-8296-0}, doi = {https://doi.org/10.1145/3437959.3459250}, pages = {165 -- 171}, year = {2021}, language = {en} } @inbook{RieblObermaierGuenther2019, author = {Riebl, Raphael and Obermaier, Christina and G{\"u}nther, Hendrik-J{\"o}rn}, title = {Artery: Large Scale Simulation Environment for ITS Applications}, booktitle = {Recent Advances in Network Simulation: The OMNeT++ Environment and its Ecosystem}, editor = {Virdis, Antonio and Kirsche, Michael}, publisher = {Springer}, address = {Cham}, isbn = {978-3-030-12842-5}, doi = {https://doi.org/10.1007/978-3-030-12842-5_12}, pages = {365 -- 406}, year = {2019}, language = {en} } @inproceedings{ObermaierRieblAlBayattietal.2019, author = {Obermaier, Christina and Riebl, Raphael and Al-Bayatti, Ali H. and Facchi, Christian and Khan, Sarmadullah}, title = {Limitations of HIL Test Architectures for Car2X Communication Devices and Applications}, booktitle = {Proceedings CSCS 2019: ACM Computer Science in Cars Symposium}, publisher = {ACM}, address = {New York}, isbn = {978-1-4503-7004-2}, doi = {https://doi.org/10.1145/3359999.3360493}, year = {2019}, language = {en} }
