This work provided an overview of the cognitive networks and systems for a wireless FI by considering the current status and looking forward at the emerging challenges. Emphasis was placed on the opportunistic networking paradigm to provide an insight on research regarding operator-governed ONs that are assumed to be coordinated extension of the infrastructure. For the coordination of operator-governed ONs, cognitive management entities are introduced. Moreover, further emphasis was placed on an operator-governed, end-to-end, autonomic, joint network and services management, which was elaborated as a part of this work. Network and services management is enabled through the definition of a UMF, which has a main goal to unify and federate various research outcomes and will advance the routine management tasks to the level of governance of the entire network.semantic.
