2nd Place Best Paper Award at IEEE World Forum on Internet of Things


20.10.2021 – We are very happy to announce that the CNI Researchers Pascal Jörke and Christian Wietfeld have received the "2nd Place Best Paper Award" for the paper "How Green Networking May Harm Your IoT Network: Impact of Transmit Power Reduction at Night on NB-IoT Performance" at the IEEE World Forum on Internet of Things (WF-IoT) 2021.


International panel on 6G organized by CNI as part of 5G.NRWeek 2021


08.09.2021 – As CNI's main contribution to this year's 5G.NRWeek, an international panel on 6G took place on 8 September 2021 as online webinar. Distinguished panel speakers from Finland, Belgium and Germany provided their long-term vision on the future development of 6G, which is expected to be launched in 2030. The slides and a recoding of the complete session will become online for those who missed the session. Already on Monday, 6 Sept 2021, a hybrid conference took place in Dusseldorf took place with Prof. Andreas Pinkwart, NRW's minister for economy, innovation, digitalization and energy, as key note speaker. Prof. Christian Wietfeld, member of the advisory board of the competence centre on 5G in NRW, participated as panelist in the session on network slicing. The recorded stream of the complete event is also available online. Finally, CNI co-organized a virtual exhibition displaying 25 5G deployment and research examples throughout NRW. The event clearly demonstrated the strength of NRW's activities on 5G and 6G networks.


CNI contributes to 6GEM research hub


29.06.2021 – With their proposal "6GEM open - efficient - secure - safe", RWTH Aachen University, Ruhr University Bochum, TU Dortmund University and the University of Duisburg-Essen were successful in a call for proposals issued by the German Federal Ministry of Education and Research (BMBF). Based on CNI's contributions to the competence center CC5G.NRW and participation in numerous 5G projects (DFG SFB 876, 5GAIN, 5Guarantee and Plan&Play), TU Dortmund University will research novel, real-time capable 6G network technologies and innovative 6G application fields, especially in close cooperation with Fraunhofer IML and the German Rescue Robotics Center (DRZ). The results will contribute to the standardization of open 6G networks (Open RAN Alliance), open source projects for software-defined networks and patents. Prof. Dr.-Ing. Christian Wietfeld will be the 6GEM spokesperson for the TU Dortmund University.


Best Student Paper Award at IEEE VTS Flagship Conference IEEE VTC-Spring 2021


10.05.2021 – We are very happy to announce that the CNI Researchers Benjamin Sliwa, Cedrik Schüler, Manuel Patchou, and Christian Wietfeld have received the prestigious "Best Student Paper Award" for the paper "PARRoT: Predictive Ad-hoc Routing Fueled by Reinforcement Learning and Trajectory Knowledge" at the IEEE Vehicular Technology Conference (VTC-Spring) 2021 which is the flagship conference of the Vehicle Technology Society (VTS) of the IEEE.


Publication on „A Low Cost Modular Radio Tomography System for Bicycle and Vehicle Detection and Classification“ to be presented on IEEE SYSCON 2021 conference


08.03.2021 – Another paper regarding CNI's research activities on a low-cost and modular radio-based detection and classification system for road users has been accepted for IEEE International Systems Conference (SYSCON) 2021. Compared to existing solutions, the proposed approach meets multiple crucial requirements, including cost-efficiency, robustness, accuracy, and privacy-preservation, while classifying heterogeneous road users (e.g., cyclists, passenger cars) accurately.


New journal article on future hybrid vehicular traffic systems accepted for publication


09.02.2021 – Although the development of fully autonomous vehicles is one of the major research topics in the Intelligent Transportation Systems domain, the upcoming long-term transition period – the hybrid vehicular traffic – is often neglected. However, within the next decades, automotive systems with heterogeneous autonomy levels and highly varying communication and coordinates capabilities will share the same road networks, resulting in new problems for traffic management systems and communication network infrastructure providers.


Publication on „SAMUS: Slice-Aware Machine Learning-based Ultra Reliable Scheduling“ to be presented on IEEE flagship conference ICC 2021


08.02.2021 – 5G network slicing is particularly important for critical infrastructure communications researched at the CNI, especially in the context of so-called "mixed-critical" services, as multiple service types such as Ultra-Reliable Low Latency Communication (uRLLC) and Enhanced Mobile Broadband (eMBB) are envisioned to be incorporated into a single physical communication network. To balance the needs of low latency slices and demanding high bitrate best effort slices, the data-driven scheduler SAMUS was developed and evaluated at the CNI, which effectively minimizes latency for critical infrastructure slices while providing the maximum data rate possible for other participants in the network based on Machine Learning.


1 Year Campus Network Planner - Unbroken high response and new 26 GHz planning aid


05.02.2021 – The Communication Networks Institute, along with the Competence Center 5G.NRW is responding to the very large response and the encouragement of now more than 9200 users, consisting of infrastructure manufacturers, network operators and primarily industrial and municipal users, and is now integrating, in addition to the new overview of previous allocation holders, a planning aid for the frequency allocation started at the beginning of the year by the Federal Network Agency for local, broadband frequency usage in the 24.25 - 27.5 GHz frequency range.


CNI Publication on efficient UAV-delivery system concept within the COVID-19 pandemic accepted at IEEE SYSCON 2021

Drone01 (2)

29.01.2021 – Solutions and concepts to alleviate the impact of the COVID-19 pandemic are also included the scope of on-going research at CNI. We are happy to announce that an article proposed by a team of our researchers (Manuel Patchou, Benjamin Sliwa, and Christian Wietfeld) was accepted at the IEEE International Systems Conference (SYSCON) 2021. A pre-print version is now available online on arXiv. The SYSCON 2021 which shall take place in Vancouver this year is currently planned as a virtual event. The contribution CNI submitted is a concept for a drone-based delivery system operating in an environment featuring constraints induced by the current COVID-19 pandemic, such as social distancing and prioritization of medical supplies.


Starting the year with 3 new projects


26.01.2021 – Good news at the beginning of the year. Grant notifications for no less than three new projects reached the institute and announce the start of all projects at the beginning of 2021. With VIZIT, as well as 5Guarantee and Plan & Play, one federally and two state-wide funded projects with focus on connectivity for automotive applications and 5G campus networks strengthen the CNI's research profile. We are looking forward to challenging research questions and a good collaboration with numerous known and new partners.
