Network and Mobility

The Competence Center “Network and Mobility” conducts research towards the overall vision of shaping the future Internet architecture and services. The research and development activities are performed within 3 main working groups (clusters), supported by inter-connected testbeds. Our innovations contribute to the architecture and services of next generation networks, while the current state-of-the-art is reflected by relevant updates and improvements on the testbed.

Semantic Media & Communications

The vision of the Semantic Media and Communications cluster is to achieve a service-level merger among heterogenous network substrates, and to design context-sensitive, personalized, and semantically rich multimedia applications over a common framework. Research and implementation activities closely follow the technologies and open standards developed by committees like 3GPP, IETF, OMA, and OSA/Parlay Group, which enable multimedia telecommunication services (call, Presence, IM) over next generation networks. The group maintains its own standards-compliant implementations of all SIP components, which are utilized and extended for further research. Semantic IPTV application is a key solution designed and developed by the group. [Read more]

Intelligent Access & Core Networks

The cluster Core + Access Networks' vision is to achieve the "always best connected" goal from users' perspective as well as the "always best managed" goal from network providers' perspective, towards next generation, converged (All-IP) network architectures. Through several projects funded at the European and national levels, the group conducts research in a broad area that includes multi-operator resource sharing and distribution in heterogeneous access networks (WLAN, UMTS, HSDPA, Flash-OFDM, WiMAX), increased intelligence in the core and at the edge of managed networks, and seamless integration of IPv4 and IPv6 networks.

Autonomous Network Architectures

The vision of the cluster Autonomous Network Architectures is to complement the virtual world of data networks with the "Internet of real things", in order to make use of the vast amount of valuable information contained within the physical world consisting of the people, the environment, the industrial products, etc. Extracting this information through emerging technologies such as RFID or sensor nodes and making it available to the rest of digital communication networks creates many new opportunities, such as smarter production and logistics in businesses, increased awareness of our environment through physical sensing and monitoring, and more efficient recovery techniques for emergency and disaster situations. Due to the large scale deployment scenarios, a key issue in this type of systems is ensuring their autonomous operation and self-configuration. Autonomous Network Architectures cluster conducts research and development in this direction.
