Probably the most important technological invention of the previous century was the
transistor. And another very important invention was the digital computer, which got a …

The author presents a unified treatment of this highly interdisciplinary topic to help define the
notion of cognitive radio. The book begins with addressing issues such as the fundamental …

Cognitive radios have been identified as a solution to the crowded spectrum issue. With the
realization of cognitive radio networks came the recognition that both new and old security …

Spectrum sensing is an important issue in cognitive radio networks. But due to noise and
shadowing effects, the sensing results of sensors may be erroneous. This will degrade the …

With the development of the mobile communication and intelligent information technologies,
the intelligent transportation systems driven by the sixth generation (6G) has many …

In cognitive radio networks, the security attacks disrupt the spectrum sensing process. One
of the most threatening attacks is spectrum sensing data falsification (SSDF) attack, where …

Cognitive radio (CR) has been introduced to accommodate the steady increment in the
spectrum demand. In CR networks, unlicensed users, which are referred to as secondary …

Spectrum sensing is the first step to overcome the spectrum scarcity problem in Cognitive
Radio Networks (CRNs) wherein all unutilized subbands in the radio environment are …

High-dimensional data usually exhibit intrinsic low-rank structures. With tremendous amount
of streaming data generated by ubiquitous sensors in the world of Internet-of-Things, fast …

In addition to standard authentication and data confidentiality requirements, Cognitive Radio
Networks (CRNs) face distinct security issues such as primary user emulation and spectrum …
