a large-scale testbed for the next generation of interoperable networks and services

Next Generation Networks consist of the convergence of all the types of networks, from cellular, broadcast to IP-based, with QoS, mobility and security functions assured, and designed to transport multimedia and data services over the same medium. The ATHENA approach is heading toward this by proposing a powerful concept of hybrid wireless metropolitan networking area that interconnects different heterogeneous networks, including the support of next generation IPv6 over broadcasting environments. Indeed, ATHENA(1) proposes broadband infrastructure for the Digital SwitchOver, transition from analogue to digital TV, enhanced by the provision of IP services. Demonstration and evaluation of a large-scale deployed testbed in the city of Heraklion, Crete, Greece, is presented.
