Telecommunications and Networks

The Telecommunications and Networks activity brings together skills at the “lower layers” (digital communications, resources allocation, etc.), the “application layer” (robust compression, content security, etc.), as well as network layers (TCP / IP, routing, etc.), which work in synergy to solve current telecommunications and multimedia problems, in particular in mobile networks. An effort is made to investigate generic mathematical tools allowing as much as possible a global optimization, such as game theory, information theory, stochastic geometry, or information geometry. In general, we aim, from fundamental research work, at further developing the results in order to bring them closer to an industrial use, in particular through collaborative contracts.

Research Teams

ILOCOS

The Information, Learning, Optimization and Communication Sciences (ILOCOS) team performs fundamental and applied research on the design of future wireless telecommunication systems. The team members apply mathematical tools such as stochastic optimization, queuing theory, information theory and machine learning to the modeling, cross-layer design, optimization and control of these systems. While the focus of the team is on 5G and 6G, other types of systems such as smart grids and social networks are also addressed.

MULTINET

The themes of the Multimedia and Networking (MULTINET) team cover a wide spectrum of activities, from network aspects to the application layer. Among the major current challenges of IoT, 5G, smart cities, energy efficiency, immersive video, real-time video transport, security or vehicle networks, our work focuses on two axes: network issues and improving video services.
