This paper investigates and proposes real-time power-splitting approach with efficient relay selection scheme for multi-terminal decode and forward ultrawideband (DF-UWB) relay network. The channel state information (CSI) technique allows for the adaptive power splitting (ASP) approach to be investigated by analyzing the adaptation of the multi-terminal relay nodes to power-splitting (PS) ratio with verifiable accomplishment in the gap between the energy-saved and the re-transmitted signal. Since the relays are multi-terminal and act as intermediaries between the source and the destination nodes, an optimal relay selection scheme is introduced to select the best relay that forwards the decoded information packets from the source to the destination nodes. Furthermore,
the need to maintain better outage performance w.r.t the multi-terminal relay network scheme is demonstrated in the simulation works while an optimized Dinkelbach (DB) iterative algorithm is introduced to maintain minimal end-to-end signal-to-noise ratio (SNR) for the multi-terminal relay links.
