Secure Cooperative Spectrum Sensing for the Cognitive Radio Network Using Nonuniform Reliability

Both reliable detection of the primary signal in a noisy and fading environment and nullifying the effect of unauthorized users are important tasks in cognitive radio networks. To address these issues, we consider a cooperative spectrum sensing approach where each user is assigned nonuniform reliabi...
