QoS feedback mechanism for a cooperative indoor D2D system

The analog to digital migration of the broadcasting technologies allows broadcasters to offer interactive services with an advanced level of personalization. Within this context, the possibility to deliver commercial content to more devices into the same domestic environment is very interesting for both consumers and service providers. Several compatibility studies have identified the joint use of detection techniques (i.e., spectrum sensing) and geo-location databases as a reliable way to enable harmless communications in the free channels in each territorial area, the so called 'TV White Spaces' (TVWS). Based on these assumptions we developed a novel cooperative system based on an Internet of Things (IoT) architecture able to involve all sensing-enabled objects in a distributed sensing procedure. In this work, we involve all IoT-enabled objects in a twofold procedure, using both spectrum sensing and Quality of Service (QoS) data delivered by the objects.
