CNI contribution to the 2nd 6G Wireless Summit

6G_Summit

28.01.2020 – We are very pleased to announce that our paper "Towards cooperative data rate prediction for future mobile and vehicular 6G networks" has been accepted for being presented at the 2nd 6G Wireless Summit. In the paper, we bring together key results of two subprojects of the Collaborative Research Center "SFB 876" and take a look beyond the ongoing 5G standardization efforts that solely focus on bringing machine learning-enabled intelligence to the network side. Using the SDR-based passive control channel sniffer FALCON, we aim to mimic the behavior of a possible future 6G deployment where the network infrastructure actively provides information about the current spectral resource utilization to the mobile clients in order to improve client-based data rate prediction for anticipatory communications. In a real world proof-of-concept study in a vehicular scenario, we were able to improve reduce the average prediction error by up to 30% through the proposed cooperative approach.

 

Release of interactive planning tool for local 5G networks

5GCampusnetzplaner_TUDo

16.01.2020 – After the much-noticed auction of 5G radio frequencies to mobile network operators in spring 2019, the Federal Network Agency launched the application procedure for additional local 5G campus networks in the 3,700-3,800 MHz frequency range in November 2019. As a consortium partner of the Competence Center 5G.NRW funded by the Ministry of Economics, Innovation, Digitization and Energy of the State of North Rhine-Westphalia, the TU Dortmund University developed the 5G Campus Network Planner, a tool with which all interested companies can determine in a few intuitive steps the expected frequency fee for the company-specific campus network.

NRW Minister of Economic Affairs and Digital Affairs Prof. Dr. Andreas Pinkwart states: "The Competence Center 5G.NRW started its work about half a year ago and supports companies and institutions in the early use of 5G. I am pleased that the work of the partners in the consortium is already bearing fruit. The 5G Campus Network Planner is a great free and user-friendly tool for quickly and easily estimating the costs of local 5G frequencies. I am confident that this nationwide unique offer will also meet with great interest beyond North Rhine-Westphalia. “

 

Master student project group C.A.R.E (Collaborative Aerial Rescue Robots in Emergency Response) successfully completed

ProjektgruppeCARE

20.12.2019 – As one of the final activities within the chair in 2019, the project group CARE (Collaborative Aerial Rescue Robots in Emergency Response) presented its final results to the members of CNI. The project group is part of the master course Electrical Engineering and Information Technology and challenges a group of students to solve a scientific task collaboratively. Within CARE, a group of 9 students realized a scaled system of ground and aerial robots which jointly executed emergency response several tasks, such as an exploration of an area affected by a natural desaster. But the highlight of the project group's presentation was surely, when two drones collaborated to synchronously transport an object within the given scenario to emulate a cleaning-up operation after a desaster. Despite the technical competencies, such as programming the control and communication of and between robots, the students also acquire practical knowledge regarding efficient project management and fruitful team work. A film about the final demonstration will soon be released on the video channel of our chair.

 

Dr.-Ing. Nils Dorsch receives dissertation award of the Rector of the TU Dortmund University

18.12.2019 – The CNI team congratulates Dr.-Ing. Nils Dorsch for receiving the award for the best dissertation in 2018/2019 within the faculty of electrical engineering and informatioon technology during the annual award ceremony of the university on December 16, 2019. Nils Dorsch's thesis is titled "Software-Defined Networking (SDN) for Real-Time Capable, Reliable and Cost-Efficient Smart Grid Communication Infrastructures" has proposed and investigated innovative concepts for communication networks suitable for the so-called Smart Grid. The work has been carried out within the interdisciplinary DFG-funded research group 1511 on "Control and protection systems for the future energy system". Dr.-Ing. Dorsch has proposed a dedicated SDN interface which enables energy system operators to control the underlying communication system through a so-called north-bound interface. The work of Nils Dorsch has attracted considerable attention: a first paper describing the overall system concept has been cited over 80 times since its publication in 2014 at the IEEE SmartGridComm conference. An analysis of the economic impact of SDN-based networks has been recently published as journal article in NETNOMICS (Springer) as well as another journal article on "Enabling Hard Service Guarantees in Software-Defined Smart Grid Infrastructures" in Computer Networks (Elsevier).

02.12.2019 – The Communication Networks Institute (CNI) receives funding notification for two interdisciplinary projects focusing on the transformative character of 5G and its impact on Smart Grid and Smart City environments. Both projects are realized in close cooperation with the Institute of Energy Systems, Energy Efficiency and Energy Economics (ie3) and strengthen the joint research activities on interactions of future energy systems and modern communication technologies at TU Dortmund University.

 

LARUS project coordinated by CNI successfully tests unmanned aircraft system over the Baltic Sea to support maritime search and rescue

LARUS-2

22.11.2019 – Three-year research project to improve communication and data exchange at sea brings important findings to practice.
Over the Baltic Sea, the German Maritime Search and Rescue Service (DGzRS), together with nine partners, has successfully tested an unmanned aircraft system for use in an emergency at sea. At the end of the LARUS (Latin: Seagull) research project, which was started three years ago, there is now an automatic fixed-wing aircraft that has already safely travelled around 660 nautical miles (about 1,220 kilometres) across the sea. An enhanced version could improve communication and data exchange in the coordination of search and rescue operations by the Maritime Rescue Co-ordination Centre (MRCC) Bremen of the DGzRS - and thus save human lives - even under difficult operating conditions. The Federal Ministry of Education and Research funded the project as part of the research program for civil security.

 

Workshop on Network Infrastructure for Cyber-Physical Systems (NI-CPS) at INFOCOM 2020 co-organized by CNI

IEEEInfocom

20.11.2019 – Modern societies are witnessing the prevalence of a wide assortment of cyber-physical systems (CPS) built upon network infrastructure for mission-critical applications, such as industrial control systems (ICS), and society-enabling services, such as intelligent transportation systems (ITS). Such applications and services may demand various levels of performance of their CPS network infrastructure, from strict and deterministic to lenient or probabilistic ones, for system agility, safety, stability and resilience. The workshop which is co-chaired by Prof. Liang Cheng from Lehigh University and Prof. Christian Wietfeld from TU Dortmund addresses is an increasing interest in modeling and analyzing network infrastructure in CPS and advancing its design and application. Contributions are invited by January 15, 2020.
