Simulating and Validating openwifi W-TSN in ns-3

As industries increasingly rely on advanced networking solutions, Time-Sensitive Networking (TSN) has emerged as an essential tool, ensuring smooth and reliable communication in mission-critical applications. However, while TSN does a lot for industrial systems, there is still a whole world of not-utilized potential in wireless communication. To extend wired TSN with wireless capabilities, imec’s openwifi platform has been extended with TSN features. To speed up the implementation of new Wi-Fi features in the openwifi platform, as well as to test their feasibility in larger-scale network scenarios we implemented the key TSN features of openwifi in the ns-3 simulator. In this paper, we evaluate how the selection of transmission opportunity (TXOP) duration affects network performance in shared time slots, as well as the impact of different shifts between shared time slots. The ns-3 implementation is validated against openwifi as well.
