In this paper, we introduce a probabilistic routing metric that considers the peculiar
characteristics of the operating environment of cognitive radio networks (CRNs). This metric …

Cognitive radio networks (CRNs) are composed of frequency-agile radio devices that allow
licensed (primary) and unlicensed (secondary) users to coexist, where secondary users …

This paper addresses the problem of optimal resource allocation in a multi-hop cognitive
radio networks. The objective of the present work is to search for the shortest possible path …

In this paper, optimal and suboptimal routing protocols are proposed for cognitive radio
networks. We first investigate optimal routing protocol that consists in searching among all …

Cognitive Radio Networks (CRNs) are an outstanding solution to improve efficiency of
spectrum usage. Secondary users in cognitive networks may select from a set of available …

Cognitive radio networks (CRNs) are group of nodes prepared through cognitive radios
which can improve the performance automatically via changing its behavior to adapt to the …

Cognitive Radio is an emerging technology to overcome the problem of spectrum scarcity
and underutilization. The vital requirement of Cognitive Radio Networks is quick route …

Cognitive radio networks (CRNs) has been popular in the field of wireless network. In CRNs,
researches focus mainly on the single hop scenes rather than multi-hop networks. Studies …

Cognitive Radio Networks (CRNs) have been receiving significant research attention due to
their ability to address the problems related with the usage ofprecious' spectrum. Majority of …
