On Cooperative Relay in Cognitive Radio Networks
Cognitive radios (CR) and cooperative communications represent new paradigms that both can effectively improve the spectrum efficiency of future wireless networks. In this paper, we investigate the problem of cooperative relay in CR networks for further enhanced network performance. We investigate how to effectively integrate these two advanced wireless communications technologies. In particula...
متن کاملTo Relay or not to Relay: Open Distance and Optimal Deployment for Linear Underwater Acoustic Networks
Existing works have widely studied relay-aided underwater acoustic networks under some specialized relay distributions, e.g., equidistant and rectangular-grid. In this paper, we investigate two fundamental problems that under which conditions a relay should be deployed and where to deploy it if necessary in terms of the energy and delay performance in linear underwater acoustic networks. To add...
متن کاملSNR Maximization through Relay Selection in Cognitive Radio Networks
In this study, we apply Artificial Bee Colony (ABC) optimization to the problem of relay selection and transmit power allocation to selected relays in non-regenerative Relay Assisted Cognitive Radio Networks (RCRNs). The objective of our proposed scheme is to maximize the Signal-to-Noise Ratio (SNR) at the secondary destination while keeping the interference offered to the primary user below a ...
متن کاملRelay Based Cooperative Spectrum Sensing in Cognitive Radio Networks
In this paper, we exploit cooperative spectrum sensing technique for applications in a relay based cognitive radio network. Relays are assigned in cognitive radio networks to transmit the primary user’s signal to a cognitive coordinator. This research is focused on the detection of primary user in single or multiple cognitive relay scenarios. The performance of energy detector is analyzed for i...
متن کاملTo Relay or Not to Relay? Optimizing Multiple Relay Transmissions by Listening in Slow Fading Cooperative Diversity Communication
The formation of virtual antenna arrays among cooperating nodes, distributed in space, has been shown to provide improved resistance to slow fading and has attracted considerable interest. Scaling cooperation in practice to a large number of participating relay nodes is an open area of research. It was recently shown that appropriate selection of a single, “opportunistic” available relay that m...
