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.

一种新的无线能量收集算法的双重讨价还价博弈范式

考虑到基于射频的能量收集技术的特点，许多智能设备都需要能量受限继电器的辅助，需要从混合接入点（HAP）中收集能量。为了设计一种新的能量收集机制，我们研究了同时无线信息和功率传输 (SWIPT) 和无线供电通信网络 (WPCN) 的集成，用于双跳无线通信。在我们提出的方案中，我们设计了一个双重讨价还价博弈范式，以自适应地为冲突的需求做出控制决策。根据两种不同的谈判解决方案，我们揭示了能量收集和信息传递的冲突关系，并制定了两个分时程序。以紧凑的迭代方式，这些程序协同工作以最大限度地提高双跳通信系统的性能。通过模拟结果，我们进行了数值分析，并证明与现有的最先进协议相比，我们的双重讨价还价方法可带来更高的系统性能。
