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 …

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 …

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 …

In this paper, we study performances of multi-hop transmission protocols in underlay
cognitive radio (CR) networks under impact of transceiver hardware impairment. In the …

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 …

In this paper, we evaluate outage probability (OP) of a cluster-based multi-hop protocol
operating on an underlay cognitive radio (CR) mode. The primary network consists of …

Multi‐hop relaying is used to extend the reach of wireless communication systems whereas
cooperative relaying is used to improve the performance gain by exploiting the spatial …

In underlay cognitive radio networks (CRNs), secondary users (SUs) have to dynamically
control their transmit powers so that the interference to primary users (PUs) is tolerable …

This paper investigates the performance of a buffered decode-and-forward (DF) relay-based
three-node underlay cooperative cognitive relay network (CRN) with a direct path to the …

A cyclic prefixed single-carrier (CP-SC) relaying system is considered for cognitive radio
networks under spectrum sharing condition. The outage probability of secondary users …
