Probability of sensing error of the proposed and conventional CSS schemes. Probability of sensing error of the direct conventional CV rule-based scheme, the cluster and global CV rule-based conventional cluster reporting scheme, and the proposed CSS schemes for different cluster sizes when the network includes five clusters with a SNR value corresponding to -20, -18, -16, -14, and -12 dB, respectively.
