ABSTRACT: The different realistic
propagation channels are faced frequently the multipath fading environments.
The main goal of this system design (cognitive radio network) is to improve the
efficiency of spectrum access on a non-interfering basis. This system achieves
high utilization for the limited spectrum in order to fulfill needs for all users’
demands which are considered as a problem in wireless communications due to
rapidly increasing in wireless applications and service. This system is exposed
to attack due to the vulnerabilities existence in this system. So, the main
outcome of this paper is to investigate the performance of the cooperative
sensing in cognitive radio networks under malicious attacks over different channel
impairments, and to illustrate the most suitable individual probability of
detection in real faded channel by using Nakagami model.
This paper illustrates the effectiveness of the attacks and fading on the
performance of spectrum sensing process.
