3 3 Overall goal Modeling, performance evaluation, optimization and control of networks Contributions Theoretical (new models, formalisms) Applied (algorithms, patents, software)

4 4 Research themes 1 - IP networks 2 - Wireless communications 3 - Information networks 4 - Game theory applied to networking 5 - Stochastic processes, queueing, control theory and game theory

5 5 1 – IP networks Content-centric networking(CCN) [In cooperation with Orange Labs, Issy-les Moulineaux] Modeling of traffic in CCNs, analysis and optimization of caching and routing policies Flow-based networking [I n cooperation with Alcatel-Lucent Bell Labs] Elaboration of new concepts for fair scheduling of flows in routers (patents with ALU) Evaluation of new TCP versions E.g. compound TCP

Wireless communications Cellular networks Green strategies for cellular networks Cell size optimization in pico-cell networks [with ALU] Spectral efficiency of CDMA uplink/downlink Cooperative and non-cooperative power control Ad Hoc, delay tolerant and mesh networks File dissemination with cooperative and non-cooperative users Routing (massively dense ad hoc networks, quasi-deterministic networks) Distributed call scheduling in mesh networks

7 7 3 – Information systems Interplay between legislation, economics and information technology Efficiency measures to enforce compliance with law Network neutrality New economical models (e.g. based on Shapley value) Social networks Clustering on the web Scale-free growing networks Analysis and enhancements of Google PageRank

Game theory applied to networking Paradigms in games theory Development of stochastic evolutionary game theory Constrained, Bayesian, partial information, potential games Application to Competitive routing Competitive access Power control Association problem in wireless Evolution of TCP in Internet

Stochastic processes, queueing, control theory and game theory Advances in game theory Evolutionary games Population games Stochastic games with delay sharing information pattern Branching processes Singular perturbation theory
