Secure 5G Wireless Communications: A Joint Relay Selection and Wireless Power Transfer Approach
IEEE Access, 2016 In this paper, we investigate the secrecy performance of an energy harvesting relay system, where a legitimate source communicates with a legitimate destination via the assistance of multiple trusted relays.

Incremental Relaying with Partial Relay Selection
IEICE Transactions on Communications, 2010 We propose an incremental relaying protocol in conjunction with partial relay selection with the aim of making efficient use of the degrees of freedom of the channels as well as improving the performance of dual hop relaying with partial relay selection (DRPRS).

Power Consumption Scheme Oriented to Full-duplex Multi-relay Cooperative SWIPT Networks [PDF]
Jisuanji kexue, 2022 In full-duplex multi-relay cooperative simultaneous wireless information and power transfer (SWIPT) networks,traditional relay selection algorithms have not taken into account the idle utilization of unselected relays.As a result,the performance waste of

Analog network coding using differential and double-differential modulation with relay selection
ICT Express, 2019 A simple relay selection scheme is proposed for analog network coding using differential modulation (ANC-DM). We propose a relay selection scheme based solely on the received signal power in which their own information is canceled out at each source node.

Relay selection algorithm based on selfish behavior analysis in ultra-dense D2D
Tongxin xuebao, 2021 In ultra-dense D2D communication, the current relay selection schemes mainly assume that the relay device has the initiative to participate in data forwarding, but some rational relay devices may delay or refuse to forward due to their own considerations,
