Description

With an increasing demand for advanced driver assistance systems, the need for reliable, robust and deterministic communication increases as well. For wired systems, solutions like TSN exist. In predictable and well-known contexts, like a factory, concepts from the wired world can be transferred to the wireless world, as proposed by the 3ggp with 5G-TSN. For other contexts, this solution is limited as some fundamental problems, like high dynamic topologies, unclear responsibility, or unclear network boundaries, lead to unknown parametrization making it extremely difficult if not even impossible to manage and configure the network.

With the “cooperativeTSN” project, we want to investigate how best-effort wireless connections can be improved in a decentralized way regarding robustness, reliability, and performance while not managing the wireless connection itself. Instead we focus on the configuration of the wired network, in order to achieve these goals.

For this purpose, existing simulation libraries like INET, Veins, and Plexe are extended to be able to simulate simultaneously the inter-car communication and the in-car communication. For scheduling, well established TSN schedulers will be used and evaluated.
