PhD Researcher Stefan Senk is a Ph.D. student at “Deutsche Telekom Chair of Communication Networks” at TU Dresden. He is working on the 5G Campus project whose goal is to develop 5G networks for industry partners. This allows to create new, innovative applications for human-robots-cooperation (cobots), for small startups or established companies. 5G communication technology is needed in order to fulfill the requirements, e.g. ultra low latency. Software defined networks, mobile edge computing and network slicing are some of the enabling technologies.
His main research interest is Time-sensitive Networking (TSN) and the integration of 5G as virtual TSN bridge.
He was born in Berlin, Germany and studied at the Technische Universität Dresden where he received his degree “Diplom-Ingenieur” (Dipl.-Ing.) in electrical engineering in July 2019. He has worked as a student helper for 3 years at Cloud & Heat Technologies GmbH, a startup company in Dresden working on the topic of sustainable green distributed cloud data centers.

Cellular-connected UAVs will benefit from ultra-reliable and low-latency communication (URLLC) in 5G and beyond networks. Their integration with Time-Sensitive Networking (TSN) via campus solutions can provide swarm robotics wireless links with deterministic behavior, flexibility, and coverage. Reliable yet cost-effective and flexible evaluation of the integration is still challenging for academia and industry. We focus on open-source testbeds due to their maturity and transparency in verifying evaluation results. Subsequently, we systematically survey and categorize testbeds in the literature that use commercial-off-the-shelf hardware. Our study outlines options for building a full-fledged testbed for integrating TSN with 5G and beyond for research and development.

Time-Sensitive Networking (TSN) is intended to enable deterministic communication over inexpensive Ethernet networks. Standardized by the IEEE TSN working group, TSN enables precise control of time synchronization, traffic shaping, reliability enhancements, and network administration to answer the demands of industrial control applications. Subsequently, there is a significant need to enable turnkey research and implementation efforts. However, a current lack of open-sourced testbed implementations to investigate and study the behavior of TSN network devices limits verification to simulation and theoretical models. We introduce a publicly available, flexible, and open-sourced measurement testbed for evaluating TSN in the context of industrial automation applications to address the need to perform real-world measurements. In this contribution, we describe our testbed combining Commercial-Off-The-Shelf (COTS) hardware and existing open-source tools as a platform for in-depth evaluation of TSN devices. Providing detailed TSN backgrounds, we describe an in-depth performance analysis for our implementation. For a common Tactile Internet scenario, we observe an accuracy of close to 5 ns achievable with our publicly available COTS setup.}, keywords = {}, pubstate = {published}, tppubtype = {inproceedings} }

Oftentimes, the timely provisioning of access to and the implementation of affordable care are drivers behind tele-healthcare initiatives. Tele-healthcare has already garnered significant momentum in research and implementations in the years preceding the worldwide challenge of 2020, supported by the emerging capabilities of communication networks. The Tactile Internet (TI) with human-in-the-loop is one of those developments, leading to the democratization of skills and expertise that will significantly impact the long-term developments of the provisioning of care. However, significant challenges remain that require today\’s communication networks to adapt to support the ultra-low latency required. The resulting latency challenge necessitates trans-disciplinary research efforts combining psychophysiological as well as technological solutions to achieve one millisecond and below round-trip times. The objective of this paper is to provide an overview of the benefits enabled by solving this network latency reduction challenge by employing state-of-the-art Time-Sensitive Networking (TSN) devices in a testbed, realizing the service differentiation required for the multi-modal human-machine interface. With completely new types of services and use cases resulting from the TI, we describe the potential impacts on remote surgery and remote rehabilitation as examples, with a focus on the future of tele-healthcare in rural settings.}, keywords = {}, pubstate = {published}, tppubtype = {article} }
