Wireless communication technologies are designed to cover specific scopes of use cases and, therefore, possess strengths and weaknesses inherent to their designated application area. As a critical enabler for robotic remote operations, wireless communications are expected to perform optimally, sometimes even in situations outside the respective technology’s intended deployment scope. Since a single technology can hardly ever meet the high requirements, various approaches to aggregate multiple communication links, so-called multi-links, have emerged in recent years. In this paper, we propose the novel open-source multi-link solution SEAMLESS to provide reliable connectivity in the context of rescue robotics in search and rescue missions. It improves flexibility by supporting general internet protocol service tunneling and multiple schedulers.

As wireless technologies can not be assessed solely on the basis of network key performance indicators, an open radio monitoring interface is implemented, allowing radio metric aware scheduling. A comprehensive evaluation is carried out in two experiments, in both indoor and outdoor testing sites. The results showcase the benefits of the proposed radio metric multilink scheduling by demonstrating a reliable high-resolution video transmission in challenging radio environments over Wi-Fi 6 and public cellular 5G.

2016 - Advancement Award Dr.-Ing. Christoph Ide

Dr.-Ing. Christoph Ide, former head of the research groups of the CNI and Alumni of SFB 876, received one of the prestigious junior awards by the Informationstechnische Gesellschaft (ITG) in the VDE for his thesis "Resource-Efficient LTE Machine-Type Communication in Vehicular Environments" in November 2016. The nationally fiercely contested award was handed over at a solemn celebration at the Berlin-Brandenburgische Akademie der Wissenschaften in Berlin on November 29, 2016. The research results of the DFG Sonderforschungsbereich SFB 876 "Datenanalyse unter Ressourcenbeschränkungen" are an excellent contribution to the development of future mobile radio-based traffic systems, which will support growing automation of the reliable, simultaneous and efficient communication between the single system components. This research also makes a valuable contribution to future 5G networks, especially in terms of the Internet of Things.

2013 ITG Awards 2013 for Dr.-Ing. Niklas Goddemeier, Dr.-Ing. Kai Daniel and Prof. Dr.-Ing. Christian Wietfeld

For their research in the field of networked robotic systems, Dr.-Ing. Niklas Goddemeier, Dr.-Ing. Kai Daniel and Prof. Dr.-Ing. Christian Wietfeld received the coveted ITG Awards 2013 by the Informationstechnische Gesellschaft in the VDE at Berlin-Brandenburgische Akademie der Wissenschaften in Berlin on November 12, 2013.

The ITG Award is being advertised annually and awarded for outstanding publications, in this case for an article in the internationally well-known IEEE Journal on Selected Areas of Communications.

Role-Based Connectivity Management with Realistic Air-to-Ground Channels for Cooperative UAVs: Ad-hoc aerial sensor networks leveraging MUAVs (Micro Unmanned Aerial Vehicles) are ideally suited to cost-efficiently explore unknown or hostile environments for example in case of incidents producing harmful gases or radiation. In this manuscript we present results on the investigations of communication-aware steering algorithms for cooperative MUAV swarms. The mission objective is to achieve a maximum spatial exploration efficiency with the simultaneous ability to self-optimize the communication links by exploiting controlled mobility. While our previous work has mainly considered the performance of the Air-to-Air mesh network, in this paper we focus on the Air-to-Ground-link connectivity control. To achieve appropriate communication links to a central sensor data sink even while exploring larger search areas, an agent-based role management strategy is used to provide suitable multi-hop connectivity. The novel algorithms are investigated for static as well as dynamically changing environments. Key results include a detailed realistic aerial channel characterization and network dimensioning analysis considering numbers of MUAVs and density of ground stations vs. exploration speed and sensor data latency.

2014 VDE-Award for Master Graduate - M.Sc. David Öhmann

Once a year, the VDE Rhein-Ruhr e.V. awards junior engineers for excellent bachelor's and master's degrees. Also this year,  the organization honored excellent degrees and continued its active dedication to young engineers. The solemn ceremony took place at the trade fair "E-world" in Essen on February 12, 2014, for the first time. For TU Dortmund, David Öhmann, whose master thesis "Kooperatives Verbindungsmanagement von heterogenen Funkzugangssystemen im Automobilumfeld" was supervised by the CNI and collaborated with BMW in Munich, has been awarded.
