Kickoff for the Digital Week Dortmund (Digitale Woche Dortmund, diwodo) at the German Football Museum #diwodo19.


05.11.2019 – The Communication Networks Institute supported the kick-off event of the third season of the Digital Week Dortmund as representative of the Competence Center 5G.NRW. This year's opening event at the DFB Museum offered a dynamic mixture of accompanying exhibition, versatile conference contributions on the topic of digital transformation and networking opportunities. In addition to an associated information desk, CNI demonstrated the potential of local 5G networks for use at major sporting events. The mobile 5G laboratory platform was used to show interested visitors the performance of new Network Slicing functionalities compared to established technologies such as Wi-Fi or LTE.


Digital Summit of the Federal Government: 5G as an Essential Base for Digital Data Platforms


29.10.2019 – At this year's Digital Summit of the Federal Government (Digitalgipfel der Bundesregierung), which took place this year in Dortmund on October 28/29, Prof. Dr.-Ing. Christian Wietfeld, Head of the Communication Networks Institute, presented the Competence Centre on 5G of the State of North Rhine-Westphalia (CC5G.NRW) to the Federal Minister Peter Altmaier and the State Minister Prof. Dr. Andreas Pinkwart, in which the Institute is significantly involved. A unique feature of the competence centre is a mobile 5G laboratory located at the TU Dortmund University, which enables companies to implement 5G applications on-site in the shortest time.


Workshop Series on "Resource constraints in data science - Recent research results and future directions within the SFB 876"


10.10.2019 – The SFB 876 has kicked off a series of workshops with dedicated themes about recent advancements in data science, artificial intelligence and adjacent disciplines within the Collaborative Research Center.
The first workshop "Resource constraints - Recent research results and future directions within the SFB 876" addresses in two sessions methods and approaches for tackling resource constraints terms of energy consumption, memory, real-time capabilities, computation efficiency and radio communication.


Four publications addressing recent topics in automotive communication networks presented at IEEE VTC-Fall 2019


10.10.2019 – Key results of the vehicular research projects "SFB 876 (B4): Analysis and Communication for Dynamic Traffic Prognosis" and "Intelligente Verkehrsinfrastruktur für sicheres vernetztes Fahren in der Megacity" (InVerSiv) were presented by CNI researchers at the IEEE VTC-Fall 2019. The IEEE Vehicular Technonology Conference (VTC) is the flagship conference of the Vehicular Technology Society (VTS) of the IEEE and took place in Honolulu during the 22nd-25th september.

Two of our contributions focus on using machine learning methods to analyze and optimize cellular vehicular communication systems. In a comprehensive real world performance analysis, we analyzed online data rate prediction in different scenarios and networks of multiple operators. Based on the foundation of the obtained results, we demonstrated Data-driven Network Simulation (DDNS) as a novel approach for accurate and fast performance optimization of opportunistic vehicular transmission schemes. Hereby, a machine learning-based black box approach is applied for modeling the end-to-end behavior of a to be optimized network performance indicator. Futhermore, we made two open source contributions to recent topics in network simulation. Lightweight ICT-centric Mobility Simulation (LIMOSim) provides an integrated framework for the joint simulation of aerial- and ground-based communication systems and targets the integration of Unmanned Aerial Vehicles (UAVs) into vehicular traffic systems. In addition, we presented an open source simulation framework for the performance analysis of Cellular Vehicle-to-Everything (V2X) Mode 4 communication which is a controversially discussed candidate system for enabling connected cars.


Successful Opening Event of Competence Center CC5G.NRW

Minister Pinkwart and CC5G.NRW Consortium

27.08.2019 – At the opening event of the Competence Center 5G.NRW, Prof. Dr. Andreas Pinkwart (minister for economics, innovation, digitalization and energy of the federal state of North Rhine–Westphalia [NRW]) informed himself on-site about the upcoming mobile network technology 5G and its innovation potential for industrial companies. The Competence Center 5G.NRW aims to support a smooth introduction of 5G and the development of NRW’s companies into a 5G lead market player.
