Requirements on the information flow for intersystem coexistence and cooperation in the emerging cognitive wireless world

The emerging cognitive wireless world considers new networking paradigms that have already started to intrigue the scientific community. In accordance to this, ETSI has proposed the Cognitive Control Network (CCN), which is based on an infrastructure-free network formation and it is an extension of the infrastructure-based Cognitive Wireless Networks (CWN) towards creating a more flexible and resource efficient, global cognitive network structure. The CCN is dynamically created, modified and terminated under the governance of CWN (governance is considered in terms of proper resources assignment, context provisioning and policies enforcement.) These are recognized as difficult management tasks that require the flow of appropriate control information among CWN and CCN and within the CCN. Framed within this statement, our work aims at addressing the requirements with respect to the control information flow for enabling the creation, modification and termination of CCN and thus, for supporting its efficient coexistence and cooperation with CWN in the emerging cognitive wireless world.
