Security-Reliability Trade-Off Analysis of AN-Aided Relay Selection for Full-Duplex Relay Networks
IEEE Transactions on Vehicular Technology, 2021This paper proposes a new artificial noise (AN) scheme that combines with the relay selection techniques to improve the physical layer security for a wiretap full-duplex decode-and-forward cooperative network. The communication consists of two phases. In

A Novel Relay Selection Algorithm for Relaying Networks
2009 IEEE 70th Vehicular Technology Conference Fall, 2009Cooperative diversity has been recently proposed as a way to form virtual antenna arrays that provide dramatic gains in slow fading wireless environments. In a multiple-relay network, the opportunistic relay selection scheme has been shown to outperform any other strategy that involves the conventional all-participate scheme.

On the selection of relays' positions in diamond relay networks
Proceedings of the 6th International Wireless Communications and Mobile Computing Conference, 2010Diamond relay network is a kind of efficient cooperative network, in which the source user selects two neighbors as relays and cooperates with both of them. In our previous work, we have studied its transmission rates for different coding and relaying schemes and proved that the performance of SRP scheme (Spatial Reuse Pattern) is better than others ...

On the Position Selection of Relays in Diamond Relay Networks
IEEE Transactions on Communications, 2011The diamond relay network is an efficient cooperative networking configuration in which the source node cooperates with two selected neighbors. For such networks, we investigate the impact of the relay positioning on the performance. In particular, considering an opportunistic protocol based on the use of relaying buffers, we provide sets of ...

Relay Selection for Energy-Harvesting Relays With Finite Data Buffer and Energy Storage
IEEE Internet of Things Journal, 2021Buffer-aided relaying can fully utilize the available selection gain of relay channels by allowing relays to store the received packets in the data buffers when the first-hop and second-hop channels are mismatched in quality.

Relay Selection Algorithm for Cognitive Relay Network
Wireless Personal Communications, 2017In the cognitive relay network, due to the different fading characteristics of communication links, not all relay nodes have constructive impacts on the system performance. A relay selection algorithm is proposed to obtain the minimum relay transmission power while satisfying the secondary user SINR requirements and interference temperature constraints.

Combined Relay Selection Enabled by Supervised Machine Learning
IEEE Transactions on Vehicular Technology, 2021Combined relay selection only requires two relays to forward signals transmitted on multiple subcarriers, but the optimal outage performance is almost surely achievable in the high signal-to-noise ratio (SNR) region.

Relay selection in multiple clustered relay networks
2015 Wireless Telecommunications Symposium (WTS), 2015We consider the downlink of a realistic cellular network composed of multiple clusters, each of which includes multiple relays and a destination terminal. In this scenario, the interference among the clusters is a critical issue, affecting the end-to-end performance of the system significantly.

Performance Analysis of Hybrid Satellite-Terrestrial Cooperative Networks With Relay Selection
IEEE Transactions on Vehicular Technology, 2020This paper conducts the performance analysis of a hybrid satellite-terrestrial cooperative network (HSTCN) having multi-antenna terrestrial relays. By assuming the availability of the direct link between the satellite and the destination, and considering
