 Obiettivo del progetto (Objective)

'Cognitive radio networking is in its infancy, but there is now an orchestrated effort to stimulate pertinent R&D activities in Europe and the US, following major regulatory initiatives to release previously reserved bands. Cognitive radio network research is now widely acknowledged to be central in enabling the next leap towards seamless spectrum/energy/cost-efficient operation and cohabitation of licensed/unlicensed operators and ad-hoc networks with only limited, if any, central coordination.

The objective of the AGILENet project is to bring together the complementary expertise of European and Third country partners and two partners in order to lay the foundations for addressing basic issues in several facets of cognitive radio networking.

The consortium consists of two European and three Third country partners, one of which is a leading wireless telecommunications industry with remarkable existing cooperation record. The partners will bring together their expertise and collaborate in order to lay the foundations for resolving basic issues in several facets of cognitive radio networking. The cross-fertilization among partners will address issues such as natural modeling and prediction of network operating point through game theoretic node interactions, the need for localized and incentive-compatible communications in an autonomic environment, topology adaptation and control, and security issues stemming from the autonomous node operation. Each partner will bring along its expertise in different thrusts, and the project will develop a unifying framework for a systematic study of the cognitive radio thrust capturing these clearly interrelated research areas.

With its suggested mobility plan, the project aspires to strengthen collaboration among partners, exploit complementarities in expertise, educate young researchers and ultimately create a solid basis for fruitful durable cooperation regime that will hopefully lead to more joint efforts in the future.'

Introduzione (Teaser)

An EU group was set up to coordinate research into the promising field of cognitive radio networking (CRN). Results consist of novel ways of utilising newly available parts of the spectrum, involving new protocols, plus improved communications secrecy.

Descrizione progetto (Article)

CRN is generally considered the future of wireless computer networking. Now that American and European regulators have made available certain hitherto restricted parts of the radio spectrum, pursuing CRN needs a coordinated research effort.

The EU-funded http://agilenet.sabanciuniv.edu (AGILENET) (Adaptive, heterogeneous, incentive-compatible, localized and secure networking) project aimed to provide such coordination. Hence, the two-member partnership intended to research fundamental CRN issues, leading to new networking protocols able to accommodate the highly variable conditions affecting CRN. The undertaking ran for three years to late 2014.

Initial work concerned development of methods to efficiently utilise the radio spectrum. The team considered contemporary systems and upcoming CRN, developing a framework for automated evaluation of various cognitive platforms. Applications include improved utilisation of the licensed and unlicensed spectra. Project research, particularly concerning full-duplex operation, extended the state of the art in spectrum utilisation.

The second research area involved developing efficient topology management protocols suitable for rapidly varying channel conditions. Studies addressed several problems affecting current and future networks. Results yielded a dynamic network-control framework where secondary users support primary users, as well as a method for improving energy expenditure.

Lastly, the team investigated communications security in agile wireless networks. Outcomes include the first dynamic control framework for a variable network and other highly technical developments that provide perfectly secret communications and networking.

The AGILENET project coordinated research efforts concerning CRN. Outcomes led to improvements in CRN spectrum utilisation, responsiveness and security.
