Abstract
An embodiment of the present invention relates to a method for performing spectrum sensing to detect a signal for a terminal of a primary user in each sensing node. The method for performing sensing may comprise the steps of: performing, by the sensing node, spectrum sensing to detect a signal for a terminal of a primary user; computing, by the sensing node, a local test statistic on the basis of the result of the spectrum sensing; calculating, by the sensing node, the transmission probability on the basis of the computed local test statistic; and transmitting, by the sensing node, sensing information to a convergence center on the basis of the calculated transmission probability. In this case, the convergence center can determine whether the signal for a primary user exists on the basis of the transmitted sensing information.
