Splitting algorithm for DMT optimal cooperative MAC protocols in wireless mesh networks [PDF]
, 2011 A cooperative protocol for wireless mesh networks is proposed in this paper. The protocol implements both on-demand relaying and a selection of the best relay terminal so only one terminal is relaying the source message when cooperation is needed.

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,

Relay Selection for Improving Physical-Layer Security in Hybrid Satellite-Terrestrial Relay Networks
IEEE Access, 2018 In this paper, a hybrid satellite-terrestrial relay network (HSTRN) interconnecting a satellite and multiple terrestrial nodes is considered, where communication is achieved by the satellite transmitting information to a destination through multiple ...

On Secure Transmission over Parallel Relay Eavesdropper Channel [PDF]
, 2010 We study a four terminal parallel relay-eavesdropper channel which consists of multiple independent relay-eavesdropper channels as subchannels. For the discrete memoryless case, we establish inner and outer bounds on the rate-equivocation region.

RELAY SELECTION IN MOBILE MULTIHOP RELAY NETWORK
Jurnal Teknologi, 2016 Mobile Multihop Relay (MMR) network is an attractive and low-cost solution for expanding service coverage and enhancing throughput of the conventional single hop network. However, mobility of Mobile Station (MS) in MMR network might lead to performance degradation in terms of Quality of Service (QoS).

On relay selection for decode-and-forward relaying [PDF]
IEEE Transactions on Wireless Communications, 2009 In this letter, we consider a multi-relay network operating in decode-and-forward mode. We propose a novel relay selection method with a low implementation complexity. Unlike the competing schemes, it requires neither error detection methods at relay nodes nor feedback information at the source.
