Cooperative communication has been proven as one of the effective spatial diversity techniques to mitigate channel impairments due to fading. In classical relay selection schemes, plenty of source nodes are supported by a best relay and the transmit power of this relay is equally divided among multiple sources, leading to a low relay power level to help each source devoted and thus an unreliable transmission...
In multi-relay cooperative networks, selecting the best relay to cooperate is known to be spectrally efficient, provided that perfect channel state information (CSI) is available for relay selection. When relays are mobile, the time-varying nature of fading channels renders the provision of accurate CSI challenging and significantly degrades the performance of best relay selection. In this paper,...
