This paper presents energy-efficient solutions for wireless sensor systems intended for the
monitoring of water quality at water stations. Energy problems, such as energy scarcity and …

The stringent requirements of wireless multimedia transmission lead to very high radio
spectrum solicitation. Although the radio spectrum is considered as a scarce resource, the …

The era of the Internet of Things (IoT) requires sustainable and convenient methods to
power widely distributed sensing devices. Self-powered systems have emerged as a …

Extending the sensor life time is one of the most important issues in widespread use of
Wireless Sensor Networks (WSNs). The Energy Harvesting (EH) sensors have been …

In this paper, we study radio frequency (RF)-powered underlay cognitive radio networks
(CRNs) with power-domain non-orthogonal multiple access (NOMA). In these networks, by …

Deep-learning methods are becoming increasingly popular for improving the efficiency of
specific emitter identification (SEI). However, in noncooperative scenarios, it is difficult to …

Recently, several Internet of Things Tools have been created, contributing to growing
network loads. To refrain from IoT should use the idea of cognitive radio networks because …

Abstract Non Orthogonal Multiple Access (NOMA) and energy harvesting are two widely
used concepts to improve the performance of Wireless Sensor Networks. In this paper, we …

Ambient backscatter communications has shown the great potentials to achieve spectrum
and energy efficient communications for future wireless networks (eg, 6G). Besides, to fully …

In this paper, we propose a cognitive radio sensor network with green power beacon (PB) to
solve spectrum and energy scarcity problems in the resource-limited wireless sensor …
