The fifth-generation mobile network (5G) supports Internet of Things (IoT) devices and
processes large-scale data volumes through mobile devices. With this facility, we find a …

This paper investigates outage and throughput performance of non-orthogonal multiple
access (NOMA) based underlay cognitive radio (ie, CR-NOMA) network under partial relay …

The problem of channel quality prediction in cognitive radio networks is investigated in this
paper. First, the spectrum sensing process is modeled as a Non-Stationary Hidden Markov …

In this paper, we consider the problem of cooperative spectrum sensing scheduling (C3S) in
a cognitive radio network (CRN) when there exist multiple primary channels. Our work …

The Internet of Things (IoT) is a rapidly growing network of interconnected devices that has
the potential to revolutionize many industries and sectors. However, IoT devices are often …

Nowadays, there are usually a huge number of sensors in most of the Internet of Things. In
this case, if a large number of nodes in the network transmit information at the same time, the …

Nowadays, the selection of relay in cooperation-based communication is a very demanding
topic in research. The choice of the relay majorly depends on various criteria; hence …

The cooperation between the primary and the secondary users has attracted a lot of
attention in cognitive radio networks. However, most existing research mainly focuses on the …

We propose cyclic prefix single carrier full-duplex transmission in amplify-and-forward
cooperative spectrum sharing networks to achieve multipath diversity and full-duplex …

In this paper, we propose a secure cooperative communications scheme for orthogonal
frequency-division multiple-access (OFDMA) cognitive radio networks (CRNs), where a …
