In the scope of cognitive radio networks, typical routing protocols avoid areas that are highly
congested with primary users, leaving only a small fragment of available links for secondary …

Current routing protocols for cognitive radio networks are severely affected by the frequent
activity of primary users. Nodes that are in the interference range of an appearing primary …

Primary user activity is a major bottleneck for existing routing protocols in cognitive radio
networks. Typical routing protocols avoid areas that are highly congested with primary users …

Cognitive radios emerged as a solution for utilizing the spectrum which is considered a
limited resource. Multi-hop routing in cognitive radio networks (CRNs) has been gaining …

In this paper, we consider a multi-channel cognitive radio network with multiple secondary
users where the channel sensing of a secondary user is imperfect. Our goal in this paper is …

Energy harvesting (EH) is a promising technology to improve both energy efficiency and
spectral efficiency in cognitive radio (CR) networks. However, due to the randomness of the …
