Location Aided Cooperative Detection of Primary User Emulation Attacks in Cognitive Wireless Sensor Networks Using Nonparametric Techniques

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
