Aim of the project

The ARAGORN project aims to explore key enabling technologies that facilitate the application of machine intelligence and adaptive communications technologies in the optimisation of resource usage in wireless networks. Most particularly, the goal is to apply methods originating from the artificial intelligence community in order to increase the efficiency and system performance of the present day and future systems following the cognitive radios and networks paradigm. The technology developed addresses the issue of increased system complexity of reconfigurable and software radio based devices and also enables co-operation between smart objects.

WP3 - Cognitive Resource Management and System Architecture

  • to evaluate existing cross-layer methods and optimisation techniques and select appropriate targets for further analysis and possible enhancement.
  • to develop the Cognitive Resource Manager (CRM) as a central entity, optimising the protocol stack of a local node as a whole.
  • to combine the CRM with the interface work done in WP2 and cooperative aspects evaluated in WP4 in order to define a common system level architecture for the ARAGORN project.
  • to investigate reasoning techniques and their appropriateness for multidimensional optimisation as is necessary to achieve optimal settings.
  • to evaluate the CRM as a whole when applying the chosen methods and techniques as part of the optimisation process.
  • to choose particularly efficient and useful cross layer methods and optimisation techniques for further integrated evaluation and partial implementation.

WP4 - Cooperative Spectrum Resource Management in ISM-bands

  • to evaluate, and possibly enhance, representation schemes for interference and spectrum occupancy information.
  • to use the current situation in ISM-bands with multiple systems working in the same frequency band as an example scenario for interworking problems between non-cooperative systems as will also occur in the case of multiple different groups of nodes opportunistically accessing the same frequency band.
  • to investigate what set of information should be shared between nodes in a cooperative manner in order to reduce interference between neighbouring nodes.
  • to develop an interface to provide context information with a clear focus on spectrum occupancy and interference information to the CRM.
  • to investigate cooperative schemes for global optimisation. In particular, lowering the overall amount of interference in the network will be one scenario.

WP5 - Prototyping and Scenarios

  • to define scenarios which clearly show the step beyond state of the art achieved with ARAGORN technology.
  • to define applications for prototyping activities.
  • to carefully select powerful and flexible prototyping platforms.
  • to develop the single components of the prototype.
  • to integrate these single components to an overall validated system.
  • to evaluate the prototype.

WP6 - Dissemination & Exploitation

  • to effectively disseminate the results obtained from the project.
  • to coordinate the exploitation of the technologies and results coming out of ARAGORN.
  • to pursue standardisation of the ARAGORN technologies.
