Ultra-densification is one of the main features of 5G networks. In an ultra-dense network,
how to conduct interference management and spectrum allocation is a challenging issue …

This paper creates a framework for spectrum sensing (SS) in localized Long-Term Evolution
(LTE)-based cognitive radios. The framework includes the formulation of various SS …

In cognitive radio (CR) networks, the role of spectrum sensing (SS) is crucial to enable an
efficient exploitation of the radio spectrum resource. The need to measure spectrum …

Spectrum sensing with single primary user (PU) has attracted the attention of researchers
due to its influence on the scarce radio spectrum. Yet, the co-existence of multiple PUs …

In underlay coexistence, secondary users (SUs) attempt to keep their interference to the
primary users (PUs) under a threshold. Due to the absence of cooperation from the PUs …

This paper studies the achievable total throughput of an energy harvesting cooperative
cognitive radio (CR) network. A CR transmitter cooperates with a primary user (PU) …

Cognitive radio networks (CRNs) mitigate spectrum scarcity by leveraging the holes in the
licensed spectrum to enable Internet of Things (IoT) devices to opportunistically access the …

A cognitive radio network has a high promise to improve spectrum utilization, through
exploitation of spectrum holes from the primary network. However, in a distributed …

Underlay coexistence is an effective mechanism to improve spectrum effïciency by having
picocells coexist with macrocell on the same spectrum. Due to a lack of cooperation …

The Cognitive Radio (CR) network is a system which lends help at the time of scarcity in
spectrum. One of the process by which CR senses the spectrum is energy detection method …
