Ziel der wissenschaftlichen Arbeiten im Bereich "Echtzeitsysteme und Kommunikation" ist es, fehlertolerante dynamische Planungsverfahren sowie Kommunikations-Technologien und Protokolle für verteilte und mobile Echtzeitanwendungen zu erforschen, zu bewerten und in realen Anwendungen zu erproben.

Computersysteme interagieren in einem immer stärkeren Maße mit ihrer Umgebung. Sie erfassen Aspekte und Informationen der realen Welt, verarbeiten sie und wirken mit ihren Ergebnissen direkt auf die reale Welt zurück. Dabei sind sie zunehmend mobil, ebenso wie die Systeme mit denen sie interagieren. Klassische Beispiele solcher Anwendungen sind die Steuerung und Überwachung technischer Prozesse und alle Arten von eingebetteten Systemen. Von größerer Bedeutung werden in diesem Bereich in Zukunft auch Robotiksysteme und – zum Teil internet-basierte – Assistenzsysteme sein, die in direkter Interaktion mit ihrer Umgebung (z.B. im Straßenverkehr) strengen Echtzeitbedingungen unterworfen sind. Diese Arbeiten finden z. Z. in den folgenden Projekten statt.

In this project we examine, how methods of data mining can be utilized to model complex processes in distributed systems. Based on these models upcoming errors and corresponding countermeasures should be identified in order to prevent a system failure. An adaptive adjustment of the generated models in a dynamic environment should be realized in further steps.

One important research goal of the group is the provision of Quality-of-Service guarantees on top of Wireless Mesh Networks. Such provisions ahe re required in many situations, including the tele-operation of mobile robots and factory automation.

The implementation of the scenario as a demonstator allows us to show the requirements imposed by these tasks on the one hand. On the other hand we are able to implement and test our research work in a real scenario, providing direct feedback for further research and giving an insight about our work to external reviewers.

Information technology systems are becoming more and more complex. Training and teaching must account to that with new application-oriented approaches. Robots obviously possess a special attraction in the context of computer science and mechatronics. The research is founded on the following hypothesis: robots as teaching tools allow making programming "understandable", they promote interdisciplinary working and social skills. The project aims to develop and test concepts and teaching materials for "autonomous mobile robots" as an innovative teaching aid.

Wireless mesh networks are a flexible way to interconnect computers in large areas or industrial facilities. The communication of the participants is controlled by a mesh routing protocol. During the development of these protocols it is essential to test them regularly under realistic conditions, to perform measurements and compare the results. Our working group is operating a test environment, which is composed of numerous stationary and mobile mesh nodes that can be positioned in the faculty building.

Wireless mesh networks are a type of infrastructure networks where the network backbone is
implemented using multi-hop wireless connections and mobile stations can maintain multiple parallel links to the network. These mesh networks offer increased flexibility and reliability compared to traditional infrastructure networks.

Wireless Mesh Networks allow the flexible connection of computers to a network backbone using cheap components. At the same time, they can be deployed as a base for QoS-demanding applications like industrial automation. AWDS is an implementation of a WMN routing daemon which can be used for additional QoS-enforcing mechanisms as well as for providing network access.
