RESEARCH ACTIVITY


The research activities that I develop while being diversified in terms of methods, techniques and applications address all the issues of management and control of future generations of wired and wireless networks and related services.

The objective is to study these problems and to propose new mechanisms, protocols, architectures and models of information allowing to solve them.

A. Autonomic Control and Virtualization of Large-Scale Networks and Services:

The objective of this line of research is to study the contribution of the new concept called "autonomic management" in the control of networks and services of the Future. The idea of ??the autonomic networks is that of a new generation of networks able to self-control and respond on their own (without intervention of a human operator) to a set of situations (breakdowns, anomalies, loss of performance, etc.) or a change of context (new traffic, new services, etc.). The aim is to find new abstract information models to model network infrastructures, services and users (operators, end-users) and then develop new reasoning mechanisms on these models in order to bring out new techniques. autonomic control that draws on other areas in which self-organization is intrinsic (e.g. biology, economics, sociology, etc.).
B. Ambient and ubiquitous network (Internet of Things):

In this second line or research, we are interested in new network architectures for setting up ambient and ubiquitous services. The basic technologies that make it possible to set up this type of infrastructure are all existing communication technologies (fixed, wireless, cellular) but also Ad-hoc communication technologies, Wireless sensors and above all the good integration and coordination between these different technologies. We mainly study the issues of mobility, multicriteria routing, distributed security and finally reducing energy consumption to increase the lifetime of communicating objects. These problems are complex once translated into an analytical form because it is not often possible to find exact solutions. Therefore, it is a question of proposing suboptimal solutions that are nonetheless realistic (having a sense in practice) and effective (cudgeled). The approach adopted consists first and foremost in dealing in isolation with the issues raised (multicriteria routing, inter-technology mobility, service discovery, energy saving, security, etc.) and then proposing integrated algorithmic, protocol and architectural solutions. Finally the validation of the proposed solutions is either analytical, or by simulation (Matlab, Opnet, P2P Sim) or by implementation in real demonstrators.
