Removing the Wires in Time-Sensitive Networks

Abstract

From machine control applications to multimedia, and distributed real-time monitoring, all require a high level of determinism and low end-to-end latency. Time-Sensitive Networking, running on top of Ethernet, has been proposed as the solution over the past years. This paper analyses the crucial challenges that need to be overcome to go beyond Ethernet and seamlessly extend such time-sensitive operation into the wireless domain. A TSN-compatible design, based on our opensource WiFi implementation, is presented, with a specific focus on scheduling. Two experiments, in our IEEE802.11-based W-TSN testbed, comparing contention arising from a shared and dedicated time slot were performed. The results show a lower difference in the number of received packets between shared and dedicated time slots at smaller time slots.
