… relays to help transmit their packets. We focus on the problem of relay selection, ie, how to
efficiently find an appropriate relay … This problem is referred to as cooperative relay selection [7…

… 3 Proposed relay selection scheme In this section, the proposed relay selection scheme
is provided. The object of this scheme is to select the node R that maximises the achieved …

… We rely on careful relay selection for protecting the ST-SD transmission against … -relay and
multi-relay selection. To be specific, only the “best” SR is chosen in the single-relay selection …

… In this paper, we investigate the performance of relay selection in an underlay cognitive radio
… multi-relay network operating in the AF mode and only one relay is selected. The proposed …

… radio systems with relay selection. In particular, they consider a secondary multi-relay
network operating in the amplify-and-forward (AF) mode and only the ‘best’ relay is selected, …

… relay selection in conventional networks, we investigate the adaptive cooperation diversity
with best-relay selection in cognitive radio networks… gain in cognitive radio networks and show …

… feasibility of relay-assisted D-OFDM by implementation in software defined radio. • We identify
new resource allocation problems in cognitive relay networks, ie, joint relay selection and …
