ARAGORN: How to Manage Cognitive Radios

Inhalt:
We summarize in this paper some of the goals and early results from ARAGORN project, which is implementing a key technological parts of cognitive radio prototype. We start by shortly discussing about different cognitive radio definitions. We specifically introduce a concept of Cognitive Resource Manager (CRM) that has been introduced by RWTH Aachen University as an architectural framework towards implementing flexible cognitive radios. We further describe the ongoing work that focused on defining necessary interfaces to manage complexity of flexible cognitive radio platforms. We also discuss about implementation challenges in our OFDM-based transceiver architecture.
