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 …

This research discusses Green Networking, an important concept in reducing the
environmental impact of information and communication technology in the digital era. In this …

Cognitive industrial Internet of Things (CIIoT) can extend available spectrum resources by
accessing the spectrum licensed to primary user (PU) on the premise of not disturbing the …

In this paper, we investigate the power allocation of primary base station (PBS) and
cognitive base station (CBS) across different orthogonal frequency division multiplexing …

In this paper, we investigate a tradeoff between the secrecy rate (SR) and energy efficiency
(EE) in an underlay cognitive radio network that consists of a cognitive base station (CBS), a …

In this article, we investigate optimal beamforming at a multiantenna primary base station
(PBS) and a multiantenna cognitive base station (CBS) for energy-efficient (EE) secure …

While designing communication systems for sustainable smart connected communities
(SCCs), energy efficiency is as important as quality of service (QoS). However, simultaneous …

The visiting and less-privileged status of the secondary users (SUs) in a cognitive radio
network obligates them to release the occupied channel instantly when it is reclaimed by the …

Spectrum handoff plays an important role in spectrum management as it is the process of
seamlessly shifting the on-going transmission of a secondary user (SU) to a free channel …

Rapid development in wireless networks has largely raised the demand for spectrum
bandwidth. However, current static spectrum allocation policy is unable to meet this ever …
