Cognitive networks and future internet
The Internet today is mainly used for global distribution of digital content objects to end users. However, the design of traditional network systems was based on the host-to-host model which has been proven ill-suited for handling large-scale content/information dissemination operations.
Future Internet technologies
In recent years, the concept of Information centric networking (ICN) has been promoted as an alternative Internet architecture in which content objects can be accessed and delivered natively according to their names rather than relying on IP addresses. In our work we have been focusing on the development of ICN-oriented network paradigms that aim to efficiently support content publication, access, storage and delivery services at the Internet scale. Specific research topics include content resolution with server and network awareness, in-network content caching, content-aware routing and mobility support. In addition, we are also investigating applied ICN principles (publish/subscribe) in other application domains such as the control of smart energy grids.
The conventional routing protocols used in today’s Internet take no account of the QoS requirements of the data or content that is to be transmitted across the Internet. We have investigated lightweight approaches for including QoS in the routing paradigms while providing excellent traffic engineering of the network. Approaches here include differentiated routing and giving some control of routing to the user, through techniques such as edge controlled routing. Approaches which allow for cooperation between the end users and the network providers are also promising.

Satellite networking
The convergence to all-IP based technology has led to major research in the same area related to satellite networking. The development of the future Internet is a very challenging task. Satellites will play a significant role in this future system and hence this is one of the major areas for research. Important topics include: integrated satellite, terrestrial, mobile and wireless networks, new services and applications such as public protection, disaster relief and management, as well as new technologies and broadband networks for ultra-high speed links.
