PROJECT TITLE :

Toward dynamic real-time geo-location databases for TV white spaces

ABSTRACT:

Recent FCC laws on TV white areas allow geo-location databases to be the only real supply of spectrum information for white area devices. Geo-location databases protect TV band incumbents by keeping track of TV transmitters and their protected service areas, based on each transmitter location and transmission parameters using refined propagation models. In this text, we have a tendency to show that keeping track of both TV transmitters and TV receivers (i.e., TV sets) can achieve significant improvement in the supply of white spaces. We have a tendency to first identify temporal and spatial wasted spectrum opportunities because of this approach to white space detection. We have a tendency to then propose our DynaWhite design, which is responsible for orchestrating the detection and dissemination of highly dynamic, real-time, and fine-grained TV white space info, based mostly on each TV transmitter and receiver information. DynaWhite proposes the event of a brand new generation of geo-location databases that mix standard geo-location databases with novel unconventional sensing approaches based mostly on the detection of passive TV receivers using customary cell phones. We tend to present a quantitative analysis of the potential gains, reaching 24 extra half-dozen MHz channels in some cases, in white house availability for potential deployments of DynaWhite. We have a tendency to finally establish research challenges related to the adoption of our DynaWhite architecture.
