EXTREME Testbed ®. Multi-purpose experimental framework for networking research
The EXTREME Testbed® is a multi-purpose reconfigurable testbed that serves to validate networking schemes in close-to-real scenarios. Beyond the general framework, it features two specialized testbeds, one focusing on cellular networks (including macro and femtocells) and a second one focusing on self-organized wireless networks. Tools have been/are being developed to achieve the two main goals of the EXTREME framework:
- Minimizing the time elapsed between conception of the scenario to be evaluated on paper and the time this scenario is deployed and ready for gathering results
- Making as independent as possible the low level details of the configuration of the machines (automated by the EXTREME framework) and the high-level design of the scenario and tests to be carried out over it. That is, researchers using the testbed should know nothing about the how (configuring the machines) and just focus on the what (specifying the scenario, running tests, and gathering results).

2009 SGR 940. Wireless communications networks and access technologies
The main activity of this research group is the study and design of wireless communications networks. In particular, the group is interested in studying access technologies as well as the associated network-related problems. Access technologies allow the end user to have access to the main telecommunications networks (telephone network, the Internet, or other proprietary networks). Network technologies deal with aspects more related to providing end-to-end connectivity, such as routing and mobility management. This research group is structured in four main research lines:
- Advanced techniques for multiuser wireless systems
- Advanced resource allocation and MAC protocols
- Self-organized networks and next generation mobile networks
- Experimental and Simulation tools
ACROPOLIS (ICT NoE)- Advanced coexistence technologies for radio optimisation in licensed and unlicensed spectrum
Wireless communications is moving towards a disruptive phase, where the speed and capability of interdisciplinary knowledge integration, for systems cooperation and coexistence, becomes a requirement for survival. This needs new thinking, and the development of architectures and facilitators for novel flexible radio technologies. To account for this paradigm shift and position Europe to benefit most from it, experts in areas of cooperation and coexistence, comprising but not limited to realms such as cognitive radio, cognitive networking and flexible networking, must integrate and harmonize their agendas.
The IP Technologies Area of CTTC is particularly involved in the following research activities:
- Activity 8.1 Machine Learning and Pattern Recognition Tools : this activity has the main objective of 1) determining the Machine Learning Techniques which are most suitable for the realization of the Cognitive Radio and Network paradigms, and 2) evaluating the real benefits of the application of these techniques in practical use cases.
- Activity 11.2: Learning Mechanisms and Exploitation of derived Knowledge : The main objective of this activity is to design and develop learning mechanisms for processing the available information gathered by different network entities and aggregating it into a unified knowledge base that can be then used for network optimization and reconfiguration purposes.
- Activity 11.3 Knowledge Networking and Sharing Knowledge networking refers to a rich and dynamic phenomenon in which knowledge is shared and evolved (i.e. updated in a collective manner).The main objective of this activity is to design and develop algorithms for distributing knowledge in selected nodes and sharing knowledge parameters in creating collective experience.

COST IC0902 – Cognitive Radio and Networking for Cooperative Coexistence of Heterogeneous Wireless Networks
The main objective of the COST Action IC0902 is to integrate the cognitive concept across all layers of communication systems, resulting in the definition of a European platform for cognitive radio and networks.
Within COST IC0902, the IP Technologies Area of CTTC is particularly involved in the following Working Groups (WGs) and Special Interest Groups (SIGs):
- WG3 Definition of network-wide mechanisms for enabling the cognitive approach : deals with all network-wide functions required for the deployment of cognitive networks, such as admission control strategies and routing policies.
- WG5 Definition of a Cognitive Engine will focus on the introduction of cognition in devices above the network layer, exploring the definition of a cross-layer cognitive engine. The Working Group will take advantage of the results obtained in the other Working Groups in order to identify the main capabilities required for the cross-layer engine to enable an effective use of available information and device characteristics, such as the presence of multiple wireless interfaces, when available, while taking into account application requirements.
- SIG2 Learning and artificial intelligence will allow experts to work together and possibly generate new knowledge towards the application of machine learning and artificial intelligence to the conception of the cognitive platform.
