Most of the ad‐hoc networks including wireless sensor network operates in unlicensed
spectrum bands (eg 2.4 GHz ISM band), which is shared by other wireless technologies …

Abstract Cognitive Radio Networks (CRNs) have emerged to overcome the problem of
spectrum scarcity caused by spreading of wireless applications. In CRNs, Secondary Users …

This paper investigates the optimal path selection problem for end-to-end (e2e) outage
probability minimization in clustered cognitive radio sensor networks. In order to improve …

An opportunistic routing problem in a cognitive radio ad hoc network is investigated with an
aim to minimize the interference to primary users (PUs) and under the constraint of a …

Cognitive Radio (CR) is a promising technology and innovative solution for current spectrum
allocation problems. We can exploit the unused licensed bands to meet the increased …

Path selection to minimize end-to-end (e2e) outage experience of cognitive users (CUs) in a
given communication session is one of the key challenges in multi-hop cognitive radio ad …

In the routing process, the cost (or weight) of routes determine via a function named routing
criterion. Therefore, the design of Optimal Routing Criterion (ORC) is one of the most crucial …

Cognitive Radio (CR) technology enables the opportunistic use of the vacant licensed
frequency bands; therefore improves the spectrum utilization. CR operation must not …

Abstract The World Economic Forum (WEF) found that Botswana's information and
communication technology (ICT) networked readiness index (NRI) had declined from …

The instability of operational channels on cognitive radio networks (CRN s), which is due to
the stochastic behavior of primary users (PU s), has increased the complexity of the design …
