Considering the characteristics of radio-frequency-based energy harvesting technology, a number of smart devices are assisted by energy-constrained relays, which need to harvest energy from the hybrid access point (HAP). To design a novel energy harvesting mechanism, we investigate the integration of simultaneous wireless information and power transfer (SWIPT) and wireless powered communication network (WPCN) for dual-hop wireless communications. In our proposed scheme, we design a twofold bargaining game paradigm to adaptively make control decisions for conflicting requirements. According to two different bargaining solutions, we reveal the conflicting relationship of energy harvesting and information transferring and develop two time sharing procedures. In a compact iterative manner, these procedures work together to maximize the dual-hop communication system performance. Through simulation results, we conduct a numerical analysis and prove that our twofold bargaining approach leads to a higher system performance compared with the existing state-of-the-art protocols.
