Pervasive wireless computing and communication have created an ever-increasing demand
for more radio spectrum. Since, most of the spectrum is underutilized, it motivated the …

IEEE 802.22 is the first standard based on the concept of cognitive radio. It recommends
collaborative spectrum sensing to avoid the unreliability of individual spectrum sensing …

Due to the high mobility, low cost and high robustness of line-of-sight (LoS) channels,
unmanned aerial vehicles (UAVs) have begun to play an important role in assisting wireless …

Cognitive Radio plays a major part in communication technology by resolving the shortage
of the spectrum through usage of dynamic spectrum access and artificial intelligence …

Cognitive radio network (CRN) enables secondary users to borrow unused spectrum from
the proprietary users in a dynamic and opportunistic manner. However, dynamic and open …

Detecting increasing anomalous signals is critical to effective spectrum management due to
the complexity of the use of electromagnetic spectrum. The anomaly recognition approach …

Many denial-of-service (DOS) attacks in wireless networks, such as jamming, will cause
significant performance degradation to the network and thus need to be detected quickly …

Several new attacks have been identified in CRNs such as primary user emulation, dynamic
spectrum access (DSA), and jamming attacks. Such types of attacks can severely impact …

In multihop ad hoc networks, a jammer can drastically disrupt the flow of information by
intentionally interfering with links between a subset of nodes. The impact of such attacks can …
