Control Channels for the Cooperation of Cognitive Management Systems (C4MS)

The exchange of information and knowledge between the CMONs and CSCIs relies on control channels (information, signalling flows and protocols) that will be built through the integration and evolution of two control concepts: the cognitive pilot channel (CPC) [1], [2] and the cognitive control radio (CCR) [1] (mentioned also in[3]). The CPC is a (logical and optionally in part a physical) channel, which provides information from the network to the terminals, e.g., on frequency bands, available Radio Access Technologies, and spectrum usage policies. Therefore, the CPC will be the basis for the coordination between infrastructure and opportunistic networks, i.e., the communication between CSCIs and CMONs. The CCR is a channel for the peer-to-peer exchange of cognition related information between heterogeneous network nodes (e.g., between terminals). Therefore, it will be the basis for the exchange of information/knowledge between the nodes of the opportunistic network, i.e., the communication between CMONs.

OneFIT will integrate and, above all, evolve the two concepts in order to obtain the C4MS. Evolutions will involve the specification of supplementary information, signalling flows and protocols (data/packet structures and exchange strategies) required for the support of the tasks suitability determination, creation, maintenance, and forced termination handling.
