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 …

Wireless communications, nowadays, becomes a vital element of people's daily life.
Providing global connectivity in future communication systems via the heterogeneous …

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 relay network is a spectrum dynamic paradigm that exploits the unused portions of
the licensed spectrum. This is based on merging both cooperative relaying techniques and …

In this study, product of two independent and non-identically distributed (inid) random
variables (RVs) for κ-µ fading distribution and α-µ fading distribution is considered. The …

A mobile device with embedded cognitive radios (CRs) is integrated into a novel low-cost
massive antenna configuration multihop or device-to-device (D2D) wireless network that …

In underlay cognitive radio networks (CRNs), transmit power of secondary user (SU) is a
function of fading channel gain between the SU and primary destination. By exploiting this …

The ergodic capacity of underlay cognitive (secondary) dual-hop relaying systems is
analytically investigated. Specifically, the amplify-and-forward transmission protocol is …

In this paper, we study the performance of cluster-based multi-hop underlay cognitive radio
network using best-last arbitrary-rest routing protocol. The exact end-to-end outage …

This paper considers a fully energy harvested two hop relay assisted cognitive radio (CR)
system operated in an underlay mode. The frame structure of the CR network consists of …
