The limited coexistence capabilities of current Internet of Things (IoT) wireless standards
produce inefficient spectrum utilization and mutual performance impairment. The problem …

In cognitive radio (CR) networks coexistence between primary and secondary networks is
allowed to exploit the spectrum bands more efficiently. To have a green CR network, energy …

Much work has been done in the area of cognitive radio networks to formulate the inherent
tradeoff among different metrics, such as sensing and throughput. Primary user (PU) traffic …

Multi-user cognitive radio networks have been considered in the literature recently.
However, there is no analytical framework which can provide a model in order to derive the …

The growing demand and wide deployment of cost effective wireless communication
networks, and the challenges related to its technical design and operations have …

This paper describes a novel scheme for the fusion of spectrum sensing information in
cooperative spectrum sensing for cognitive radio applications. The scheme combines a …

Coexisting with a dynamic primary user network is a challenge in cognitive radio networks,
since the rate at which primary user reoccupies the spectrum is high. Therefore, it is …

Cognitive radio network explores the framework for energy harvesting and derives effective
algorithms such as Nash Equilibrium re-Optimization, Greedy one-slot Game, and Bi Layer …
