In this paper, we study the performance of a cluster-based multihop underlay cognitive radio
network using an ad-hoc routing protocol (called max-link-selection protocol) with decode …

Multihop relaying is used for increasing the communication range of cognitive radio
networks. To circumvent the implied loss in throughput due to multihop relaying, in this …

Cognitive radio and energy harvesting are two important approaches to solve the problem of
spectrum scarcity and energy constraint in wireless communications. In this work, we study a …

In this work, we examine the interference alignment (IA) performance of a multi-input multi-
output (MIMO) multi-hop cognitive radio (CR) network in the presence of multiple primary …

With growing demands for mobile data, providing reliable communication with high quality of
service has become a critical issue. Wireless relaying has been recognized as an effective …

In this paper, a bidirectional relay cooperation scheme in underlay cognitive radio network
(CRN) is studied, in which two secondary users (SUs) nodes exchange information through …

In this paper, we consider a cooperative multi-hop cognitive radio network (CRN) where
multiple isolated multi-hop paths are present between a secondary transmitter and a …
