Abstract
We consider the problem of spectrum sensing in cognitive radio networks under model uncertainties, i.e., the distribution under null hypothesis and the alternate hypothesis is not known. We model the presence of the primary signal as a mean change problem. Two simple nonparametric sequential algorithms for testing the mean are proposed. These nonparametric algorithms are applied to a decentralized detection framework. These algorithms show better performance than some of the existing nonparametric tests in literature. The performance of these algorithms is analysed via theory and simulations.
