4 Main research areas Heterogeneous networks Different technologies and types of networks Ad-hoc and mesh networks Different methods of exploiting communication QoS architectures Seamless mobility Privacy Multicast and broadcast New network architectures Integrated mobility, multihoming, QoS in intelligent and mobility-driven architectures. New technologies for high speed access. Generic approaches able to seamless operate in different types of networks. Information-centric architectures Cooperation between users, operators, coexistence Clean-slate approaches... How to evolve without being tied to TCP/IP stack... 4

5 Mobility, Privacy Seamless mobility in heterogeneous networks Fast mobility mechanisms, technology independent, with quality of service Multi-interfaces and multihoming support Mobility in multicast services environments Always best connection algorithms New mobility architectures Simplification of the mobility process Mobility with privacy How to uncorrelate mobility processes between different identities Identity-based mobility Identity-based architectures Inter-domain mobility 5
