On the impact of jamming attacks on cooperative spectrum sensing in cognitive radio networks

Cognitive Radio (CR) Networks have been identified in recent literature as having great potential in realizing distributed shared communications, especially the ability to ensure broadband access of limited resources by opportunistically sharing spectrum with the incumbent users. Since the CR uses wireless communication and inherits all of its associated security threats, it is of paramount importance to fully investigate the impact of malicious faults like jamming attacks on CR networks under different fault scenarios. This research investigates CR Networks in the presence of Jamming attacks based on fault-model classification. A hybrid Jamming mitigating approach is proposed to better handle the affect of malicious jamming nodes under consideration of hybrid fault models.
