Keywords:
C2C (Car to Car); C2I (Car to Infrastructure); Simulation
Duration:
4.3.2009 - 31.12.2010
Project Description:
Notice traffic blocks before they are visible. Recognise risky situations before they get out of hand. Reach your destination fast, safe and relaxed. This vision of safe and intelligent mobility motivates our research project simTD. The vision can be made real with the help of electronically connected vehicles and infrastructure: car-to-x communication.
The simTD test field is located in the Frankfurt-Rhine-Main area of Hesse. With up to 400 vehicles and more than 100 ITS Roadside Stations installed by the Hessian traffic centre (VZH) and the Integrated Traffic Management Center Frankfurt (IGLZ), car-to-x communication will be tested under real conditions.
Audi AG is working with the Computer Networks and Communication Systems group in two areas:
-
IT-security of simTD:
This topic covers the provision of integrity, authenticity, confidentiality and privacy during and after the use of simTD applications. The questions are addressed by a conceptual architecture and specific solutions, which can be mapped to the envisioned applications.
-
Simulative exploration of system parameters:
This topic covers the identification of candidate system parameters, a partial implementation of relevant simTD applications, and the simulative exploration of these parameters to derive optimal settings. Based on these studies, the applicability of simTD applications can be evaluated, software optimized, and field trials parameterized.

Keywords:
C2C (Car to Car); C2I (Car to Infrastructure); 3G+; UMTS; IP-based communication protocols for telematic applications; simulation; cross-layer design and optimization
Duration:
1.11.2006 - 30.4.2009
Project Description:
Cooperatively acting vehicles represent a substantial innovation for future traffic management solutions and for the next generation of driver assistance systems. Including efficient communication mechanisms into future cars can be seen as a central task. This comprises both the direct (or indirect) vehicle to vehicle communication (C2C) as well as the vehicle to infrastructure communication (C2I) for sending and analyzing real-time traffic conditions in order to generate and broadcast important traffic information.
Main questions that CoCar will tackle by means of simulation studies and cross-layer optimization techniques are (among others):
- Which effects are to be expected for the network signalling and which protocols have to be provided to support future telematic applications?
- Which latency and load behaviour patterns are induced by CoCar application scenarios?
- Which additions/changes at existing system concepts are to be accomplished and which requirements arise for future, network-supported communication services?
- How can traffic status information be acquired automatically in real-time and provided for CoCar users inside the cars by using UMTS services?
The research work in CoCar is driven by an interdisciplinary, internationally acting consortium, consisting of prominent telecommunication network operators, network equipment suppliers as well as car and truck manufacturers. Industrial research is thereby supplemented by university research partners that preparatory work in the form of distinctive subcontracts.
The objectives and ambitions of CoCar are put high and aim on making Germany the technology leader within the range of C2C and C2I applications based on cellular mobile UMTS communications. The final goal is to develop an open European standard to export vehicle communication solutions into future European cars.

HISTORY - HIgh Speed neTwork mOnitoRing and analYsis
Project Management:
Project Participants:
Project Description:
The aim of this project is to build an architecture, methods, and tools for distributed network monitoring and analysis. The HISTORY architecture allows gathering information about network traffic at high-speed and at distributed network monitors. The monitoring information is delivered to one or more collectors for further analysis using standardized protocols such as IPFIX (IP Flow Information eXport) and PSAMP (Packet SAMPling). Envisioned applications are accounting and charging, attack and intrusion detection, and traceback.Visualization techniques and anonymization methods round off the big picture. The studied analysis methods are validated in experimental environments as well as in simulated networks. Finally, we also investigate solutions for remotely configuring distributed network monitors.
The developed methodologies for monitoring, storing, analyzing high numbers of packets and flows are suitable for deployment on inexpensive low-end hardware. All published tools will be available under an open source license. The usage of standard protocols allows deploying other standard-conform products and implementations within our architecture and makes it possible to use selected components of our architecture in other contexts as well.
