Due to the under-utilization problem of the allocated radio spectrum, cognitive radio (CR)
communications have recently emerged as a reliable and effective solution. Among various …

Traditional power grids are currently being transformed into smart grids (SGs). SGs feature
multi-way communication among energy generation, transmission, distribution, and usage …

In cognitive radio networks (CRNs), multiple secondary users may send out requests
simultaneously and one secondary user may send out multiple requests at one time, ie …

In this survey paper, we characterize the learning problem in cognitive radios (CRs) and
state the importance of artificial intelligence in achieving real cognitive communications …

For conventional wireless networks, the main target of resource allocation (RA) is to
efficiently utilize the available resources. Generally, there are no changes in the available …

Time-critical and delay-sensitive multimedia applications require more spectrum and
transmission resources. With the provision of cognitive radios (CRs), the underutilized …

Compressive sensing (CS) has received much attention in several fields such as digital
image processing, wireless channel estimation, radar imaging, and cognitive radio (CR) …

A cognitive radio wireless sensor network is one of the candidate areas where cognitive
techniques can be used for opportunistic spectrum access. Research in this area is still in its …

Wireless networks with their ubiquitous applications have become an indispensable part of
our daily lives. Wireless networks demand more and more spectral resources to support the …

Spectrum inference, also known as spectrum prediction in the literature, is a promising
technique of inferring the occupied/free state of radio spectrum from already …
