Notation  Description 

 Number of spectral bands to be sensed 
 Number of sensing SUs in a given time epoch 
 Group SNR 
 Average probability of the detection of the group 
 Average probability of false alarm of the group 
 Network size (integer) 
 Probability of detection of fused data obtained by fusing inputs 
 Probability of false alarm of fused data obtained by fusing inputs 
 Size of majority, depends on average and of the group. 
 Observation interval as an integer number of time epochs 
 Risk factor 
 Minimal number of SUs required to maximize the network utility 
 Desired probability of sensing equal to 
 Average probability of sensing, averaged over time epochs 
 Network utility function with active (sensing) users 
 Network utility function with each SU sensing with probability 
 Resource efficiency 
 Certainty factor = 
 Weightage given to the accuracy and resource efficiency . 
 Average probability of detection of the of ith SU 
 Average probability of false alarm of the ith SU
