The digital transformation of society as a whole is placing considerable demands on connectivity. That's why we need robust, reliable network infrastructures - the backbone of the telecommunications industry. Faced with fast-growing demand, networks must therefore evolve rapidly, a move partly driven by the advent of 5G. But the fifth generation of mobile networks must itself overcome a number of challenges. How can network architecture be adapted to this new context? How can we optimize the use of resources? How can we reduce the environmental impact of digital technology?
New generations of networks are also opening up new prospects. New uses and new users - connected objects - are becoming increasingly important, as part of the Internet of Things (IoT). But this is not without impact on networks, which have to cope with unprecedented constraints, particularly in terms of reliability, interoperability, responsiveness and security. As for the objects used, they must be able to function while obeying inherent hardware imperatives. In particular, they have to adapt to the limited amount of energy available to them, which means, for example, restricting the bandwidth needed for data transmission as much as possible, while guaranteeing the security of the information exchanged.
Researchers at Carnot Télécom et Société numérique are working to meet these challenges through their research work. To do so, they regularly collaborate with major industry players and standardization bodies, contributing their expertise and a multidisciplinary approach. In this way, they are helping to make networks and the Internet of Things more reliable and secure, notably through virtualization techniques, machine learning methods, innovative flexible microelectronic devices...
Possible applications
- Optimizing the use of network resources, through equipment virtualization.
- Responding to new requirements by evolving network architectures towards agile, distributed systems.
- Continuously adjust 5G networks to fluctuating demand, using mathematical analysis and artificial intelligence tools.
- Making optical networks, which play an essential role in 5G, more flexible and intelligent, via software control and virtualization solutions.
- Improving the energy efficiency, interoperability and security of the Internet of Things, via a data compression protocol.
- RFID wireless technology for battery-free energy supply to connected objects.
- Adapting connected objects to the context in which they evolve (industry 4.0, connected agriculture, smart cities...).
