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 …

Energy efficiency in cellular networks is a growing concern for cellular operators to not only
maintain profitability, but also to reduce the overall environment effects. This emerging trend …

Wireless sensor networks (WSNs) use the unlicensed industrial, scientific, and medical
(ISM) band for transmissions. However, with the increasing usage and demand of these …

Internet of things (IoT) paradigm poses new challenges to the communication technology as
numerous heterogeneous objects will need to be connected. To address these issues new …

In this correspondence, an adaptive cooperation diversity scheme with best-relay selection
is proposed for multiple-relay cognitive radio networks to improve the performance of …

A green-energy-powered cognitive radio (CR) network is capable of liberating the wireless
access networks from spectral and energy constraints. The limitation of the spectrum is …

Dynamic spectrum access has been a subject of extensive study in recent years. The
increasing volume of literatures calls for a deeper understanding of the characteristics of …

In order to mitigate the shortage of wireless spectrum, the appealing concepts of cooperative
communication techniques and cognitive radio (CR) networks have been combined for the …

Relays receive and retransmit signals between one or more sources and one or more
destinations. Cooperative relaying is a novel technique for wireless communications that …
