Distributed spectrum sensing for indoor broadcasting services using an IoT platform

The switch to digital broadcasting technologies has allowed broadcasters an advanced level of personalization and interactivity. The possibility to deliver commercial content to more devices into the same domestic environment, excites both consumers and broadcasting service providers but is hindered by the lack of available RF spectrum. In this context, TV White Spaces (TVWS) are an ideal candidate for deploying interactive indoor broadcasting services, based on firm rules to avoid service disruption for broadcasters, by using joint spectrum sensing techniques. This paper proposes a distributed spectrum sensing method based on an IoT architecture. The architecture comes in support for short-range video broadcasting for delivering commercial contents to several TV devices in an indoor scenario, involving several sensing-enabled objects in a joint manner.
