الملخص EN

A cognitive radio network (CRN) with a cooperative spectrum sensing scheme is considered.

This CRN has a primary user and multiple secondary users, some of which are malicious secondary users (MSUs).

Energy detection at each SU is performed using a p-norm detector with p≥2, where p=2 corresponds to the standard energy detector.

The MSUs are capable of perpetrating spectrum sensing data falsification (SSDF) attacks.

At the fusion center (FC), an algorithm is used to suppress these MSUs which could be either an adaptive weighing algorithm or one of the following: Tietjen-Moore (TM) test or Peirce’s criterion.

This is followed by computation of a test statistic (TS) which is a random variable.

In this paper, we assume TS to have either a Gamma or a Gaussian distribution and calculate the threshold accordingly.

We provide closed-form expressions of probability of false alarm and probability of miss-detection under both assumptions.

We show that Gaussian assumption of TS is more suited in presence of an SSDF attack when compared with the Gamma assumption.

We also compare the detection performance for various values of p and show that p=3 along with the Gaussian assumption is the best amongst all the cases considered.
