Consequently, it requires a technical infrastructure that can support the agile deployment of these concepts and corresponding high-level applications, which, e.g., demand the processing of massive data in motion and at rest. As such, key research aspects are the support for low-latency control loops, concepts on scalable data stream processing, deployable information security, and semantically rich and efficient long-term storage. In particular, such an infrastructure cannot continue to be limited to machines and sensors, but additionally needs to encompass networked environments: production cells, edge computing, and location-independent cloud infrastructures. Finally, in light of the envisioned WWL, i.e., the interconnection of production sites, the technical infrastructure must be advanced to support secure and privacy-preserving industrial collaboration. To evolve today’s production sites and lay the infrastructural foundation for the IoP, we identify five broad streams of research: (1) adapting data and stream processing to heterogeneous data from distributed sources, (2) ensuring data interoperability between systems and production sites, (3) exchanging and sharing data with different stakeholders, (4) network security approaches addressing the risks of increasing interconnectivity, and (5) security architectures to enable secure and privacy-preserving industrial collaboration. With our research, we evolve the underlying infrastructure from isolated, sparsely networked production sites toward an architecture that supports high-level applications and sophisticated digital shadows while facilitating the transition toward a WWL.

However, today’s static grid protection cannot manage all upcoming conditions while providing a high level of dependability and security. It forms a bottleneck of a future decarbonizing grid development. In our research project, we develop and verify an adaptive grid protection algorithm. It calculates situation dependent protection parameters for the event of power flow shifts and topology changes caused by volatile power supplies due to the increase of renewable generation and the rapid expansion of e-mobility. As a result the distribution grid can be operated with the optimally adapted protection parameters and functions for changing operating states. To safely adjust the values on protection hardware in the field, i.e., safe from hardware failures and cyberattacks, we research resilient and secure communication concepts for the adaptive and interconnected grid protection system. Finally, we validate our concept and system by demonstrations in the laboratory and field tests. ven2us Proceedings of the CIRED workshop on E-mobility and power distribution systems 2022, June 2-3, 2022, Porto, Portugal Porto CIRED workshop on E-mobility and power distribution systems 2022 June 2-3, 2022 10.1049/icp.2022.0768 1 MatthiasLorenz Tobias MarkusPletzer MalteSchuhmacher TorstenSowa MichaelDahms SimonStock DavoodBabazadeh ChristianBecker JohannJaeger TobiasLorz MarkusDahlmanns Ina BereniceFink KlausWehrle AndreasUlbig PhilippLinnartz AntigonaSelimaj ThomasOffergeld inproceedings 2020-henze-ccs-cybersecurity 2020 11 9 Mitigating cybersecurity threats in power distribution grids requires a testbed for cybersecurity, e.g., to evaluate the (physical) impact of cyberattacks, generate datasets, test and validate security approaches, as well as train technical personnel. In this paper, we present a blueprint for such a testbed that relies on network emulation and power flow computation to couple real network applications with a simulated power grid. We discuss the benefits of our approach alongside preliminary results and various use cases for cybersecurity research and training for power distribution grids. https://www.comsys.rwth-aachen.de/fileadmin/papers/2020/2020-henze-ccs-cybersecurity.pdf ACM

For this reason, offering frameworks, which are capable of addressing multiple layers of applications on the one hand and providing means of data security and privacy for ubiquitous dataflows on the other hand, is an important step to enable the envisioned advances. In this context, welding production has been introduced from the perspective of interlaced process layers connecting information sources across various entities. Each layer has its own distinct challenges from both a process view and a data perspective. Besides, investigating each layer promises to reveal insight into (currently unknown) process interconnections. This approach has been substantiated by methods for data security and privacy to draw a line between secure handling of data and the need of trustworthy dealing with sensitive data among different parties and therefore partners. In conclusion, the welding production has to develop itself from an accumulation of local and isolated data sources towards a secure industrial collaboration in an Internet of Production.

Lifting these limitations brought about by this artificial set-up would allow us to perform neuropsychological assessments and research in mobile settings or at locations easier accessible to patients, possibly even in remote, hard to access areas. We developed a tablet based mobile framework to present auditory and visual stimuli, capture wireless commercial EEG and screen interaction data, and analyze the recorded data for immediate evaluation, as well as share the data over internet or local opportunistic links. To demonstrate the feasibility of our approach, we successfully replicated the experimental set-up and evaluation pipeline of two existing EEG studies on event-related potentials. This work therefore lays the foundation to further truly mobile brain research and health-care applications. fileadmin/papers/2014/2014-bitsch-extremcom-mobile-eeg-demo.pdf Online Hui, Pan and Lindgren, Anders ACM Proceedings of the 6th Extreme Conference on Communication Galapagos Islands, Ecuador 6th Extreme Conference on Communication August 11-15, 2014 en 978-1-4503-2929-3 1 Jó AgilaBitsch Link RoannRamos DavidOrlea KlausWehrle techreport 2013-schmidt-rtp-extended 2013 12 20 AIB-2013-19 arXiv:1312.5892 [cs.NI] 1--24 refector fileadmin/papers/2013/2013-schmidt-aib-rtp.pdf Online Department of Computer Science, RWTH Aachen

While such means are essential to overcome distances, using infrastructure services for location-based services may not be desirable. In this paper, we analyze a fully distributed variant of an ephemeral content sharing service, solely dependent on the mobile devices in the vicinity using principles of opportunistic networking. The net result is a best effort service for floating content in which: 1) information dissemination is geographically limited; 2) the lifetime and spreading of information depends on interested nodes being available; 3) content can only be created and distributed locally; and 4) content can only be added, but not explicitly deleted. First we present our system design and summarize its analytical modeling. Then we perform extensive evaluation for a map-based mobility model in downtown Helsinki to assess the operational range for floating content, which, at the same time also validate the analytical results obtained for a more abstract model of the system. https://www.comsys.rwth-aachen.de/fileadmin/papers/2011/2011-percom-vaegs-floatingcontent.pdf Online IEEE

We integrate the KleeNet symbolic execution engine with the COOJA network simulator to allow for straight-forward and intuitive high-coverage testing initiated from a simulation environment. A tight coupling of simulation and testing helps detect, narrow down, and fix complex interaction bugs in an early development phase. We demonstrate the seamless transition between COOJA simulation and KleeNet symbolic execution. Our framework enables future research in how high-coverage testing tools could be used in cooperation with simulation tools. kleenet fileadmin/papers/2010/2010-osterlind_sasnauskas-sensys-coojakleenet.pdf Print ACM

To further increase flexibility, we believe cross-layer architectures should adapt themselves to these changing conditions, just as they adapt the network stack, devices, and applications. In this paper, we propose CRAWLER, a novel cross-layer architecture that combines three core properties: signaling between all layers and system components; extensibility and adaptability at runtime; and high usability for cross-layer developers. CRAWLER increases flexibility, as well as expediting and simplifying cross- layer development.

The space and weight constraints resulting from the size of the animals have led to simple but functional approaches for vocalization classification and position estimation. For the resulting data we have developed novel, delay-tolerant routing and collection strategies. These are expected to be used in a sparse, dynamic network resulting from various rats being tagged with our nodes and running around freely - an area that will eventually be too big to be covered solely by stationary data sinks. Furthermore, the system is designed to extract information on the social interactions between animals from the routing data. It currently works in an indoor environment and we are preparing it for tests in a controlled outdoor setup.

For this purpose we are using wireless sensor networks, monitoring various quantities that yield important information to complement current knowledge on the behavioral repertoire of rats. So far, on the sensing and processing side we have developed innovative, minimalist approaches pointing in two directions: vocalization analysis and movement tracking. On the data collection and routing side we have adapted to the known burrowing habits of rats by developing new methods for synchronization and data aggregation under the paradigm of sporadic connectivity in a sparse, dynamic network.

To study this behaviour, we will resort to the use of wireless sensor networks, monitoring various quantities that yield important information to complement current knowledge on the behavioural repertoire of rats. The challenges we face include data acquisition and processing on the one hand, as rat-borne sensor nodes will need to be small enough not to interfere with the rats' own activities, thus limiting the available memory and processing capabilities. Additionally, rats spend a significant amount of time underground, making data transmission and routing a very interesting challenge, for which we are currently developing novel strategies.

Typical wireless data communication will not only occur in short range scenarios like hotspots in airports, city centres, exhibition halls, etc., but also in wide area environments, e.g. a moving car in a rural environment. Data services will require a ubiquitous mobile radio system and demand better quality of service, like high data rates and low delays. Two promising concepts for future mobile radio communication are the deployment of relays and the ability to adapt to various deployment strategies by using different radio access technologies, i.e. modes with a common technology basis. The former concept allows enlarging the cell coverage. Relays are not wired connected and consequently a cost-efficient alternative to base stations that work in a decode-and-forward principle. The latter concept provides modes that are tailored solutions for specific environments and thus allow the adaptation to various scenarios by selecting the most adequate one. The aim of this work is to merge the advantages taken from both concepts to one solution. Wireless Communications and Networking Conference, 2007.
