The proposed solution is based on a flexible cooperation between providers, operators, and end-users, finally enabling every user first to access the offered multimedia services in various contexts, and second to share and deliver his own audiovisual content(More)
—The paper presents an infrastructure-based cognitive radio network architecture that enables for TV white spaces exploitation, QoS provisioning and policy management, under the real time secondary spectrum market policy. It describes the configuration of a spectrum broker that coordinates the radio resource management process (RRM) among LTE secondary(More)
The paper introduces and validates a concept concerning the realization of a fusion IP/DVB networking environment that supports urban and rural always-on connectivity and triple-play services provision. Specifically, the proposed fusion environment realises a unified infrastructure that mutates traditional passive urban citizens to active Information(More)
