Cognitive radio is emerging as one of the most promising aspects regarding the efficient usage of the radio spectrum and also on a non-interference basis. However the most challenging part is the effective detection of primary users (PUs). Nowadays there are a lot of threats from attackers who use techniques like data falsification, primary user emulations to cause harm to the users, so we need to address them with proper and efficient solutions. So in this survey we address the various threats and the challenges faced in cognitive radio environments and also we are here to discuss the various sampling techniques that could be used for the purpose of proper detection.
