With the increase in user demand for internet access on move, spectrum resource seems to
deplete and leads to spectrum crunch. Recent researches reports that this spectrum crunch …

Effective utilization of spectrum resources is an important factor in wireless communication
which reduces spectrum scarcity. Over the years, communication systems use different …

Absract Cognitive Radio Sensor Network (CRSN) is a promising solution to overcome
spectrum under-utilization and spectrum scarcity in a resource-constrained Wireless Sensor …

Currently, there are saturated frequency bands that affect the quality of service for new
users. Cognitive radio provides an alternative solution to this problem through dynamic …

In cognitive radio networks (CRNs), the resource allocation is viewed as a multi‐objective
optimisation problem in terms of limitation of quality of service, the capacity of a channel and …

Over the past few years, dynamic spectrum access has been gaining an increasing attention
as a solution to the spectrum scarcity problem. In this paper, a primary user detection …

Wireless communication systems primarily depend on the availability of bandwidth.
Cognitive radio has been realized as an effective means to maximize the bandwidth for …

Abstract In Cognitive Radio Network, after sensing process, the selection and decision for a
reliable channel from the list of free channels is important for assignment to Cognitive Users …

La decisión espectral es un aspecto clave para mejorar el desempeño en las redes de radio
