In this paper, an amplify-and-forward (AF) cooperative strategy for interference limited
networks is considered. In contrast to previously reported work, where the effect of …

In this paper, we consider a heterogeneous ad-hoc network where primary users may
cooperate with cognitive radio (CR) users for the transmission of their data. We propose a …

This paper deals with protocol design for cognitive cooperative systems with many
secondary users. In contrast with previous cognitive configurations, the channel model …

In this work, a cognitive cooperative communication protocol is proposed for cognitive ad-
hoc networks, in which primary users and cognitive radio (CR) users may cooperate for …

In cognitive radio networks, cognitive secondary users (CSUs) can interfere with the primary
users (PUs) when they falsely occupy the PU's licensed spectrum. If CSUs in transmission …

We consider a cognitive setting composed of multiple primary frequency bands each of
which consists of a limited-battery energy-harvesting primary user and a secondary user …

The cooperation among the secondary users or among the secondary users and the primary
users have proven to bring many benefits to both primary and secondary users in cognitive …

Many earlier works have studied the problem of cooperative spectrum sensing in cognitive
radio networks. However, relay selection was not considered which can improve the …

We assume a set of cognitive relay nodes that assists both primary and secondary
transmissions in a time-slotted cognitive radio networks. To regulate the channel access of …
