It is widely accepted that the architecture of next generation of mobile wireless systems will be based on seamless connectivity to the Internet as its primary focus, and the Internet Protocol (IP) suite as its core building block. Nonetheless, important issues remain to be resolved, all rooted in the need to support seamless, secure and flexible value-added services. The goal of this project is to find innovative solutions for the issues faced by IP-based network architectures. These include providing infrastructure support for peer-to-peer and emerging novel application paradigms, rapid deployment of network features and facilities, seamless mobility for entire sub-networks such as those in trains and airplanes, secure fast handoff with minimum burden imposed on end terminals, and end-to-end Quality of Service (QoS). In addition, a longer view necessitates investigation of protocol architectures where the original elegance and slimness of the IP protocol "waist" is restored by techniques such as identity-based networking and sub-IP mechanisms.
