SMART: Intelligent Multimedia Routing and Adaptation based on Service Specific Overlay Networks

Inhalt:
This paper presents early results of the Ambient Networks Integrated Project in the area of multimedia routing and adaptation in self-configuring Ambient Networks (ANs). ANs integrate heterogeneous underlying wired and wireless networks to provide global connectivity and advanced services for mobile users and service providers. This work introduces novel concepts for cooperative, self-organizing networks, which offer optimized media delivery mechanisms for point-to-point and mass distribution (broadcast/multicast) services. This is achieved by a novel overlay network technology, which enables controlled integration of advanced media routing, adaptation and caching mechanisms along the end-to-end media delivery path. Thus, in contrast to today’s end-to-end media delivery concepts, the network takes an active role in the delivery of content and services.
