Relaying protocol design and optimization for energy harvesting relaying in SWIPT networks

Abstract In this article, a relaying network with simultaneous wireless information and power transfer (SWIPT) is considered, where the relaying nodes are energy‐constrained. The relaying nodes rely on energy harvesting (EH) technique for energy supply and they use different directive transmitters f...
