“…In SYN-MAC, channel hopping sequences were created in a round-robin fashion that required tight synchronization among SUs, which is difficult to achieve in an ad hoc environment. In [21], the authors proposed biased pseudo-random sequences. These sequences do not need tight synchronization, but the average TTR may not be bounded.…”

In cognitive radio or dynamic spectrum access networks, a rendezvous represents meeting two or more users on a common channel, and negotiating to establish data communication. The rendezvous problem is one of the most challenging tasks in cognitive radio ad hoc networks. Generally, this problem is simplified by using two well-known mechanisms: the first uses a predefined common control channel, while the second employs a channel hopping procedure. Yet, these two mechanisms form a life cycle, when they simplify the rendezvous problem in cognitive radio networks. The main purpose of this paper is to point out how and why this cycle forms.

“…Game theory and Q-learning algorithm are often utilized to discuss attacker-SU action patterns [9] and to detect selfish users [10]. In confront of common control channel jamming attack, traditional communication technique of channel hopping is proved efficient for SUs exchanging channel information via multiple common control channels stochastically [11]. From the perspective of intrinsic features of CRNs, to the best of our knowledge, no universal anomaly detection scheme has been proposed.…”

Cognitive radio networks (CRNs) have been recognized as a promising technology that allows secondary users (SUs) extensively explore spectrum resource usage efficiency, while not introducing interference to licensed users. Due to the unregulated wireless network environment, CRNs are susceptible to various malicious entities. Thus, it is critical to detect anomalies in the first place. However, from the perspective of intrinsic features of CRNs, there is hardly in existence of an universal applicable anomaly detection scheme. Singular Spectrum Analysis (SSA) has been theoretically proven an optimal approach for accurate and quick detection of changes in the characteristics of a running (random) process. In addition, SSA is a model-free method and no parametric models have to be assumed for different types of anomalies, which makes it a universal anomaly detection scheme. In this paper, we introduce an adaptive parameter and component selection mechanism based on coherence for basic SSA method, upon which we built up a sliding window online anomaly detector in CRNs. Our experimental results indicate great accuracy of the SSA-based anomaly detector for multiple anomalies.

“…So, using sequenced base rendezvous method can be effective here, because meanwhile, the delay caused by control channel is more than rendezvous algorithm. After sensing such situation, the users starts generating sequence based frequencies ( [14], [15] provide optimum sequence generation details). As mentioned before, users will find each other after a while and will continue transmission during TI.…”
