SenseLess: A Database-Driven White Spaces Network

The FCC ruling on Nov 4th, 2008 on white spaces has opened up the possibility of wireless network deployments over white spaces, i.e., vacant UHF TV channels. A key requirement for any white space device (WSD) is that it must ensure that none of of its transmissions interfere with incumbents, namely TV transmitters and wireless microphones. The FCC ruling proposes two techniques for WSDs to meet these requirements: spectrum sensing and the use of a geo-location database. A host of prior work has focussed on building better spectrum sensing techniques for WSDs to determine those parts of teh spectrum that are currently occupied by primaries. While potentially feasible, this approach is technically challenging. Hence, in this paper we propose SenseLess, an alternate design and approach towards building a white spaces network. As suggested by the very name, in SenseLess, WSDs rely less on spectrum sensing to determine white spaces availability. Instead, they primarily rely on a combinati...
