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

摘要

This paper presents a novel wireless access point architecture designed to support the development of next generation mobile context-aware applications over metropolitan scale areas. In addition, once deployed, this network will allow ordinary citizens secure, accountable and convenient access to the Internet from their local city and campus environments. The proposed architecture is based on an approach utilising a modified Mobile IPv6 protocol stack that uses packet marking and network level packet filtering at the edge of the wired network to achieve this objective. The paper describes this architecture in detail and contrasts it with existing systems to highlight the key benefits of our approach.
