The growing number of users relying on wireless networks to access the Internet is imposing new challenges to both technological and architectural aspects of today systems. An evolution to a more flexible self-organized and self-maintained architecture, where mesh networking and seamless mobility are of paramount importance, is seen as inevitable. This paper addresses a new architecture based on self-organized principles and IPv6, where service support is handled at a higher abstraction level. In this context, solutions for the addressing scheme, mobility support, self-organization and node interconnection are proposed. A prototype was developed as a proof of concept and performance measurements were obtained from a given set of scenarios. Main results showed acceptable performance (e.g. 20 ms for average session establishment) on the majority of the scenarios.
