Research Activities

Inter-working between emerging communications technologies.

This topic includes a general framework of Self-Organization and Self-Optimization Networks (SONs). The main interest is to design new adaptive and predictive online algorithms to build X-efficient RRM (including Joint RRM and Common RRM) methods and protocols for sparse and dynamic networks.

Automation through learning

Dynamic Fractionnal Frequency reuse

Wireless communications and intermittent connection networks.

By lack of persistent end-to-end connection, several routing protocols in wireless networks fail to sustain communication between end-users. The focus here is to consider new types of networks such as Delay Tolerants Networks (DTNs) where the design and optimization of new routing protocols will help to construct efficient alternative networks.
