In this paper, we analyze the performance of an energy harvesting (EH)-assisted overlay
cognitive non-orthogonal multiple access (NOMA) system. The underlying system consists of …

Cooperative and cognitive non-orthogonal multiple access (CCR-NOMA) has been
recognized as a promising technique to overcome spectrum scarcity and massive …

The heterogeneity nature of networks is the most eminent characteristic in 5G vehicular
cognitive radio networks across complex radio environments. Since multiple communicating …

Position awareness is very important for many sensor network applications. However, the
use of Global Positioning System receivers to every sensor node is very costly. Therefore …

In this paper, we study the application of the non orthogonal multiple access (NOMA) and
orthogonal multiple access (OMA) scheme to cooperative cognitive radio network. We …

The deployment of Secondary Networks (SNs) gives an energy and cost-saving outcome for
service providers. The existing research on SNs is gleaned from capacity enhancement …

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

Wireless sensor location is a challenging task issue in the Internet of Things (IoT). Distance
vector-hop (DV-hop) algorithm provides a range-free positioning scheme, but its position …

In wireless communication, radio access is a key and important technology. Cognitive Radio
(CR) and non-orthogonal multiple access (NOMA) are two promising technologies for next …

This article studies the physical layer security in a downlink full-duplex cognitive non-
orthogonal multiple access sensor networks (FD-C-NOMA). Compared with the existing …
