The vacant or under-utilized TV bands are resourcefully operated by cognitive radio permitted IEEE 802.22 Wireless Regional Area Networks (WRANs). Conversely due to the nature of cognitive radio networks and absence of active security protocols, the IEEE 802.22 networks are exposed to several Denial of Service (DoS) threats. In this paper, the target band for DoS attack is a particular band called as most user band which has maximum number of operators between the existing sub bands in the CR network.
