In this work, three specific machine learning techniques (neural networks, expectation
maximization and k-means) are applied to a multiband spectrum sensing technique for …

Cognitive radio (CR) networks are an emerging and promising technology to improve the
utilization of vacant bands. In CR networks, security is a very noteworthy domain. Two …

In this paper, we present an efficient allocation of power and channel so that power-drained
primary users can harvest energy from secondary systems through wireless power transfer …

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 is an important way to improve spectrum efficiency and spectrum sensing is
the key technology of cognitive radio. However, the performance of spectrum sensing only …

Physical layer (PHY) security that is based on information-theoretic secrecy has recently
emerged as an alternative option for traditional cryptographic techniques to secure wireless …
