Vehicular Communications

There is a cooperation with the automotive industry over several years mainly in terms of joint Ph-D. projects with the Audi AG in the context of the INI.FAU program (http://www.ini.fau.de/) in which we examine a broad range of automotive topics. Example project have been: transmission of safety-relevant data, model-based development of a safety computer, simulation of traffic flow information, security in traffic flow information systems, testing with Markov chain usage models, forecasting of traffic light phases, testing for future safety electronics, concurrency in timed usage models for testing, data quality and control of automotive manufacturing, and evaluation of the benefit from inter-vehicular communication on electric vehicles.

Smart Energy Systems (Smart Grid)

Renewable energy generation is fluctuating, the mismatch between offer and demand can be resolved either by control of conventional power plants, by energy storage or by shifting load peaks on the demand side. The growth of renewables also needs more decentralized coordinated units (e.g. in houses or communities) instead of large centralized ones. For the complete system of merging electrical and communication networks, of various storage technologies and the remaining efficient usage of fossil fuels, simulation models are being developed: on a smaller scale for microgrids (combined producers and consumers which try to remain self-sufficient) and on a larger scale for the main aspects of the energy system of a complete region like a state.

Industrial Communications and Sensor Networks

Specialized busses as well as Ethernet are common communication technologies in automation and both need to satisfy specific requirements, e.g., for the latencies of sent messages. Besides simulation models for wireless communications according to IEEE 802.15.4 and ZigBee we use network calculus as an analytic approach for establishing real-time guarantees in wired communications. This is done in a cooperation with the Siemens AG.

Mobile ad-hoc networks (MANETs) solve given tasks cooperatively without a central entity. The task of the infrastructure-less network is to robustly transfer information from the data-source to the data-sink and, if required, mutate it alone the way. Certain scenario-driven requirements, like energy-awareness, must be observed.  In order to maximize availability in unknown networks it is required to continuously update neighboring information. For mobile and battery driven nodes those two features do not go hand in hand and, thus, represent a challenging tradeoff. MANETs are classically located in the 2D domain, utilizing only a limited mobility. Amongst others, we extend the state of the art by pushing MANETs into 3D space were continuous movement is mandatory.

Test-Driven Agile Simulation

Test-driven agile simulation combines simulation and model-based testing in order to provide mutual benefits for both and in order to define a new approach for systems engineering with improved quality assurance. For this purpose system models and test models with a user perspective (usage models for short) are being developed in parallel and iteratively. The complete approach is based on UML2.

Scientific overview

Successful coorperation with thyssenkrupp

The Tech-Center Control Technology of the thyssenkrupp AG assigned Computer Science 7 to analyze the optimal dispatch of a cement plant by a combined optimization and simulation model. Mainly cost reduction potentials should be determined by optimizing the cement production considering the integration of storage within the whole production process. Furthermore, a redox-flow batterie and a wind powerplant were added to the cement plant in order to determine possible cost savings by reducing the grid power supply on the one hand and beeing able to offer frequency restoration reserve power on the other hand. The results showed that a significant decrease of electricity supply cost per produced ton cement is possible under certain conditions. For more detailed information please take a look at the paper presented at the Energieinformatik 2016 conference and the article in the technology magazine techforum published by thyssenkrupp AG.

5th GI/ITG KuVS Fachgespräch Inter-Vehicle Communication

The chair of Computer Science 7 (Computer Networks and Communication Systems) organized the 5th GI/ITG KuVS Fachgespräch Inter-Vehicle Communication (FG-IVC 2017), April 6-7 2017. Under the presence of a local television channel, numerous participants from the IVC-Community were initially inspired by a very interesting impulse speech by Dr. Sigfried Balleis (former mayor of the city of Erlangen and team member of the "German Innovation Lab"). Afterwards, young researchers have presented and discussed their current research topics. Further information: http://www7.cs.fau.de/fgivc2017

Kolloquiumsvortrag: 22. März, Andreas Buck

Evaluation of Adaptive Channel Access Mechanisms in Vehicular Ad-hoc Networks
Vehicular Ad-hoc Networks (VANETS) are one of the most topical subjects in current transport system research. Especially for safety applications, it is of paramount importance to make perfect use of the given wireless channel capacities. Therefor mechanisms, that provide an optimal channel behavior towards the criteria of those applications are highly appreciated.
In this bachelor thesis, we will have a look at the principles of VANETs, that lead to the necessity of introducing new congestion control algorithms. After that, two of such mechanisms, namely Limeric and Dynb, shall be examined theoretically and simulative. The simulative evaluation will be realized by expanding the Veins-Framework for vehicular network simulation by those. Scenarios and metrics have to be determined to classify their efficiency. On the other hand, weaknesses should be exposed and possible improvements to fix the failure can be introduced.

Kolloquiumsvortrag: 15. März, Christian Estelmann, Untersuchung von kooperativen Unfallvermeidungsalgorithmen unter Berücksichtigung der Fahrzeug-zu-Fahrzeug-Kommunikation

Untersuchung von kooperativen Unfallvermeidungsalgorithmen unter Berücksichtigung der Fahrzeug-zu-Fahrzeug-Kommunikation

Aktuelle Kollisionsvermeidungssysteme sind bisher darauf beschränkt, nur das eigene Fahrzeug beeinflussen zu können. Mit Hilfe der V2V-Kommunikaiton können Absprachen mit benachbarten Fahrzeugen getroffen und hierdurch der Handlungsspielraum zur Kollisionsvermeidung erweitert werden. Es ist somit möglich, dass mehrere Fahrzeuge simultan und koordiniert eine Handlung ausführen, um eine Kollision zu vermeiden. In dieser Arbeit werden verschiedene Planungsalgorithmen miteinander verglichen. Zur Kollisionsvermeidung müssen bestimmte Schritte nacheinander ausgeführt werden. Bei diesen Schritten handelt es sich um Gruppenbildung, Manöverplanung und Verständigung auf Umsetzung mit abschließender Durchführung. Es wird erarbeitet, zu welchem Zeitpunkt diese Schritte durchgeführt werden müssen. Die Algorithmen werden auf die Leistungsfähigkeit hin untersucht, in verschiedenen Szenarien Ausweichmanöver zu finden, ohne die Algorithmen auf ein spezielles Szenario zu optimieren. Die Kommunikation zwischen den Fahrzeugen ist hierbei essentiell. Es wird analysiert, welche Kommunikationsmöglichkeiten unter welchen Rahmenbedingungen die Anforderungen des Systems erfüllen.
