A novel approach to secure cognitive radio network using dynamic quiet period scheduling for detection of control channel jamming attack

摘要

Cognitive radio is an emerging technology in the area of wireless communication. IEEE 802.22 WRAN is a first newly established standard for cognitive radio to provide broadband internet access in rural areas. While considering this, security of cognitive radio network is the major concern. For the coordination of network function, common control channel facilitates exchange of control messages. Because of its importance, this channel could be a key goal of jamming attacks. This paper proposes countermeasure to control channel jamming attack. In 802.22 WRAN system quiet period frame exists in every superframe. During this quite period frame spectrum sensing is carried out for primary user detection. Through this paper, we would like to introduce the similar kind of concept using dynamic quite period scheduling for the detection of control channel jamming attack. Detailed simulation results prove the effectiveness of our method.
