射频（RF）能量传输和收集技术最近已经成为为下一代无线网络供电的替代方法。由于这种新兴技术能够实现无线设备的主动能量补充，因此它在支持具有服务质量要求的应用方面是有利的。在本文中，我们提出了一个全面的文献综述的研究进展，在无线网络的RF能量收集能力，这是被称为RF能量收集网络（RF-EHNs）。首先，我们提出了一个概述的射频EHN，包括系统架构，射频能量收集技术，和现有的应用。然后，我们介绍了电路设计的背景以及最先进的电路实现，并回顾了专门为RF-EHN设计的通信协议。我们还根据网络类型探讨了RF-EHN开发中的各种关键设计问题，即，单跳网络、多天线网络、中继网络和认知无线电网络。最后，我们展望了一些开放的研究方向。
Radio frequency (RF) energy transfer and harvesting techniques have recently become alternative methods to power the next-generation wireless networks. As this emerging technology enables proactive energy replenishment of wireless devices, it is advantageous in supporting applications with quality-of-service requirements. In this paper, we present a comprehensive literature review on the research progresses in wireless networks with RF energy harvesting capability, which is referred to as RF energy harvesting networks (RF-EHNs). First, we present an overview of the RF-EHNs including system architecture, RF energy harvesting techniques, and existing applications. Then, we present the background in circuit design as well as the state-of-the-art circuitry implementations and review the communication protocols specially designed for RF-EHNs. We also explore various key design issues in the development of RF-EHNs according to the network types, i.e., single-hop networks, multiantenna networks, relay networks, and cognitive radio networks. Finally, we envision some open research directions.
