Presentation

The LIMOS laboratory (Computer Science, Modelling and Systems Optimisation Laboratory) is a Mixed Research Unit (MRU 6158) in computer science, and more generally in Information and Communication Sciences and Technologies (ICST) at the University Clermont Auvergne.

LIMOS focuses on the following themes:

• Combinatorial optimisation,
• Algorithms, Graphs, Complexity
• Metamodelling, Continuous Optimisation and Application (MCOA)
• Data, Services and Intelligence
• Networks and Security
• Modelling and Optimisation of Manufacturing Systems
• Service Design and Planning

As part of the Networks and Security theme, LIMOS maintains a research activity on wireless networks and cybersecurity. In general, we seek to develop communication technologies in order to make them more reliable, more efficient and more secure.

As part of the C-ITS projects, the University Clermont Auvergne participates in the study of the wireless technologies used. More specifically, we are looking at whether the technologies used (in particular, ITS-G5 and LTE-V2X) can meet the constraints of the applications deployed in these projects. We are also working on decision-making methods for choosing the best access technology at a given time for a given application. This involves verifying the performance requirements of the various applications in terms of error rate, access delay and throughput, and then using tests to check whether these performances can be achieved by these technologies in typical scenarios. It should be noted that different applications have different performance requirements. For example, a collision avoidance application has greater constraints in terms of access delay and loss rate than an application that announces the closure of a lane.
