Evaluation of Most User Band (MUB) Attack in a Cognitive Radio Network Based on Sub-Nyquist Sampling

The unused or under-utilized TV bands are opportunistically utilized by Cognitive Radio enabled IEEE 802.22 Wireless Regional Area Networks (WRAN). However, due to the nature of cognitive radio networks and lack of proactive security protocols, the IEEE 802.22 networks are vulnerable to various Denial of Service (DoS) threats. In this paper, the target band for DoS attack is a specific band called as Most User Band which has maximum number of users among the available sub bands in the CR network. The authors propose a countermeasure strategy (Time concealment strategy), to counter the MUB attack.
