Due to the under-utilization problem of the allocated radio spectrum, cognitive radio (CR)
communications have recently emerged as a reliable and effective solution. Among various …

Cognitive radio (CR) has emerged as a promising technology to exploit the unused portions
of spectrum in an opportunistic manner. The fixed spectrum allocation of governmental …

Spectrum decision is the ability of a cognitive radio (CR) to select the best available
spectrum band to satisfy secondary users'(SUs') quality of service (QoS) requirements …

Abstract Cognitive Radio Networks have been emerged as a promising solution for solving
the problem of spectrum scarcity and improving spectrum utilization by opportunistic use of …

Channel bonding (CB) is a proven technique to increase bandwidth and reduce delays in
wireless networks. It has been applied in traditional wireless networks such as cellular …

Cognitive radio networks challenge the traditional wireless networking paradigm by
introducing concepts firmly stemmed into the Artificial Intelligence (AI) field, ie, learning and …

In this paper, we present an analytical framework to design system parameters for load-
balancing multiuser spectrum decision schemes in cognitive radio (CR) networks. Unlike the …

Wireless access networks are often characterized by the interaction of different end users,
communication technologies, and network operators. This paper analyzes the dynamics …

A cognitive network makes use of the information gathered from the network in order to
sense the environment, plan actions according to the input, and make appropriate decisions …

Wireless sensor networks (WSNs) are an integral part of our daily life activities. The vast
urbanization of population has provoked the need for smart cities. The applications of WSNs …
