Modeling
The pressure of the economic stakes is such these days that the performance evaluation of systems has become an inescapable and highly strategic domain. In fact, it is inconceivable to construct any system (whether it be a computing system, a communication network or a manufacturing system) without first conducting performance analyses; an undersized system will be unusable, and an oversized system will be financially wasteful. Research at the Networks and Performance Analysis group focuses on the Internet of the future and aims at developing solutions in order to build it and dominate it. To this end, the goal of this activity is to develop analytical models for both wired and wireless communication networks, in order to evaluate their performance and help in dimensioning them. Several research axes are currently under investigation and concern wired networks, ad hoc networks and cellular networks (GSM/GPRS/EDGE/UMTS). The objectives of all these axes are always to develop simple models in order to provide both a meaningful qualitative analysis of the fundamental behavior of the system and a fast quantitative analysis of its performance. Most of the techniques that are used come from the Stochastic Processes, Markov Chain and Queuing theories.
