A Double Adaptive Approach to Tackle Malicious Users in Cognitive Radio Networks

Algorithm 1

Proposed algorithm at fusion center.
Input: energy of the sample (mass value  ), lowest threshold (thr1), highest threshold
(thr2)
If energy of the sample (mass value) < lowest threshold (thr1)
Set the corresponding weights to zero
Else if lowest threshold (thr1) < energy of the sample (mass value) < highest threshold (thr2)
Update masses value using (6)
Else
Don’t update mass values
End if
Output: Update mass value .
