An instantaneous transmission mode analysis in energy harvesting for half-duplex and full-duplex relaying network

Abstract

Energy harvesting (EH) based on surrounding radio frequency (RF) has lastly become advanced approach to prolong the lifetime of the wireless networks. This paper deals with energy harvesting architecture of the half duplex and the full duplex relaying networks. By applying time switching based relaying (TSR) protocol and Amplify-and-Forward (AF) scheme, we derive the closed-form expression of the instantaneous throughput and then compare instantaneous throughput of two networks. An important result can be seen clearly that the time fraction, the position of relay, noise at relay, energy conversion factor as well as target rate in TSR impact on their throughput. Finally, numerical results show an efficient relaying strategy in half-duplex and full duplex cooperative networks.
