...Still, it can only be used for short distances, up to D_max=11 mm. When the D_max increases, selecting a higher BW will not be optimal because the achieved channel rate is less than the required data rate. Therefore, lower BW should be used at longer distances, with the price of consuming higher energy due to longer pulse duration TP. When the Dmax increased, the model used a larger number of nano-relays to reduce the distance between every pair of communicating nano-nodes. The smaller distances will enable the nano-nodes to operate at higher BW and, hence, at the shortest possible pulse duration TP_w which will minimise the overall energy consumption in transmitting/receiving bits. Results show that there is no BW less than 25 GHz is selected, which utilised lower channel bandwi...
