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.
