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

Algorithm 1

Parametric PUE attack detection.

Inputs:

PU position:

Set of SU positions: ,

Vector of RSS values:

Parameters of the path loss model: and

Detection threshold:

Steps:

(1) Obtain the PU to SUs distances , .

(2) Compute the test statistic using (11).

(3) if    then

(4)  attack_flag ← true

(5) else

(6)  attack_flag ← false

(7) end if

(8) return  attack_flag
