The benefits of cognitive radio networking (CRN) have been well recognized with the
emerging wireless applications in recent years. While many existing works assume that the …

In this paper, we investigate joint relay selection and power allocation to maximize system
throughput with limited interference to licensed (primary) users in cognitive radio (CR) …

Cognitive Radio (CR) is an attractive technology to deal with current spectrum scarcity
problem, while cooperative relay can make distributed receivers benefit from spatial diversity …

In this paper, we investigate the joint optimization of sensing and power allocation for
cooperative relay in cognitive radio networks (CRNs). Specifically, in the sensing time slot …

Cognitive radio networks using relays have been introduced to enhance secondary network
performance by having secondary users (SUs) transmit in two hops. This paper develops a …

In the underlay decode-and-forward (DaF) cooperative cognitive radio (CR) network, an
optimal relay can be selected by the conventional max-min selection on the condition of not …

In this study, the author investigates the outage performance of cognitive relay networks, in
which the best relay is selected based on full and partial channel state information …

In this paper, we present a distributed relay selection and power allocation scheme
concurrently considering the channel states of all related links and residual energy state of …

Integrating simultaneous wireless information and power transfer (SWIPT) into cooperative
cognitive radio networks (CCRN) can increase both energy and spectral efficiencies. In …

In this paper, an adaptive two-way relay cooperation scheme is studied for multiple-relay
cognitive radio networks to improve the performance of secondary transmissions. The power …
