A wireless public access infrastructure for supporting mobile context-aware IPv6 applications

This paper presents a novel wireless access point architecturedesigned to support the development of next generation mobilecontext-aware applications over metropolitan scale areas. Inaddition, once deployed, this network will allow ordinary citizenssecure, accountable and convenient access to the Internet fromtheir local city and campus environments. The proposed architecture is based on an approach utilising amodified Mobile IPv6 protocol stack that uses packet marking andnetwork level packet filtering at the edge of the wired network toachieve this objective. The paper describes this architecture indetail and contrasts it with existing systems to highlight the keybenefits of our approach.
