Algorithm 2
Nonparametric PUE attack detection.
Inputs: | PU position: | Set of SU positions: , | Vector of RSS values: | Detection threshold and “PFA adjustment” parameter: , | Steps: | (1) Obtain the PU to SUs distances , . | (2) Compute the test statistic using (16). | (3) if then | (4) attack_flag ← true | (5) else if then | (6) attack_flag ← true with probability | (7) else | (8) attack_flag ← false | (9) end if | (10) return attack_flag |
