Mobility is, without doubt, one of the major new paradigms of the current Internet, and this is driving most of the research activity in networking throughout the World. We are gradually evolving from a network where most end-systems have a fixed or quasi-fixed point of attachment, towards a global network where end systems seamlessly move from network to network and where networks themselves change their connection point to the Internet. In spite of this there is still a long way to go before user and network mobility – at IP level – become a reality, as several technological and research challenges persist.

The current talk addresses the above challenges at various levels. After briefly providing some background on user and network mobility, an overview of the state-of-the-art is presented. Next, mobility research challenges and approaches are addressed under various perspectives, in connection with several key problem areas, namely quality of service routing in mobile ad-hoc networks, use of mobile IPv6 and soft hand-off in wireless sensor networks, interaction between multi-homing and mobility and, last but not least, route optimisation for network mobility.
