To support the massive connectivity in Internet of Things (IoT), several promising techniques
like cognitive radio (CR) and non-orthogonal multiple access (NOMA) enables the user to …

Short-packet communication is an important feature of the Internet of Things (IoT). For
allowing massive IoT devices to connect to a network through short packets, this paper …

Non-orthogonal multiple access (NOMA) is considered a potential technique in fifth-
generation (5G). Nevertheless, it is relatively complex when applying NOMA to a massive …

The Internet of Things (IoT) has attracted significant attentions in the fifth generation mobile
networks and the smart cities. However, considering the large numbers of connectivity …

Abstract Presently, Secondary Networks (SNs) are gleaned from rising capacity with
reducing interference together instead of making them energy-efficient for green …

In this work, an uplink secondary Internet of Things (IoT) device scheduling and power
allocation problem based on imperfect channel state information (CSI) and imperfect …

The cooperative non-orthogonal multiple access (NOMA) networks with one pair primary
user and one pair cognitive user share the same spectrum resource via a common relay is …

To compensate for the transmission efficiency in a cooperative non-orthogonal multiple
access (NOMA) system, we enable in-band full-duplex (IBFD) and two-way cognitive …

In this article, we investigate the performance of spectrum sharing inunderlay cognitive radio
(CR)-inspired nonorthogonal multiple access (NOMA) systems, at which a primary …

Cognitive radio non-orthogonal multiple access (CR-NOMA) networks promise improved
spectrum utilization and capacity in 5G networks. In this work, we aim to investigate efficient …
