Opportunistic networks (ONs) are considered as coordi-nated extensions of a radio access network infrastructure, which are dynamically and temporarily created in an infra-structure-less manner in order to increase service reachabil-ity, improve resource utilization efficiency and facilitate lo-calised service provisioning. The realization of the ON con-cept relies on the existence of control channels which will provide necessary signalling for the coordination of the ON nodes. Proposed control channels are conceived as an evo-lution of the already established cognitive pilot channel concept. As a result, new interfaces are discussed in order to convey information from the infrastructure to the terminals and vice versa or between terminals. Finally, the business benefits of the aforementioned approach are provided in order to strengthen the notion of the proposed control chan-nels and consider future expansions. 1.
