It is expected that the wireless world will migrate towards an era that will comprise more local/ temporary structures for the provision of services. A networking paradigm towards this direction is the opportunistic networking. Operator-governed ONs are dynamically created, temporary, coordinated extensions of the infrastructure. Operator governance is being realized through the use of Cognitive Management Systems which acquire the context, policies and profiles of the environment and make decisions on the creation of opportunistic networks. The paper presents an approach for exploiting such ONs in order to extend the capacity in wireless access and backhaul segments for efficient application provisioning, as well as an evaluation of indicative test cases as a proof of concept of the aforementioned approach. All these scenarios will enable the cognitive cloud-oriented vision of wireless networks for efficient application provisioning in the Future Internet era.
