This textbook introduces Wireless Powered Communication Networks (WPCNs) as a promising paradigm to overcome the energy bottleneck suffered by traditional wireless communication networks, as well as emerging Internet-of-Things networks. It selectively spans a coherent spectrum of fundamental aspects in WPCNs, such as wireless energy transfer (WEH) techniques, radio frequency (RF) energy harvesting receiver model, simultaneous wireless information and power transfer (SWIPT), as well as the rate-energy tradeoff arising from the joint transmission of information and energy using the same waveform. It covers network models for WPCNs, including the baseline and dual-hop WPCN models and a variety of related extensions. This book further examines the key factors including throughput, fairness, and security that must be taken into account for impeccable operation of WPCNs. The new IoT applications are targeted as a key element in those factors. It will also include exercises and examples throughout the book, as well as their PLS solutions.
This is the first textbook examining the current research to provide a unified view of wireless power transfer (WPT) and information transmission in WPCNs from a physical layer security (PLS) perspective. Focused on designing efficient secure transmission schemes, analyzing energy evolvement process, and evaluating secrecy outage performance under different channel state information (CSI), the results presented in this book shed light on how to best balance security and throughput with prudent use of harvested energy in WCNs. It also provides an overview of the WPCNs by introducing the background of WPT, followed by a summary of the research conducted in the field. The authors describe the physical-layer security (PLS) problem in WPCNs, including the causes and the impacts of the problem on the performance of WPCNs. The authors extend the discussions by introducing the applications of WPCNs in the IoT.
From the Internet of Things (IoT) point of view, this textbook reviews the opportunities and challenges for the lately-emerged WPCN to seamlessly integrate into the IoT ecosystem. It specifically addresses the maximization problem of uplink and downlink sum-throughout in a dual-hop WPCN, while taking fairness among WPCN users as a constraint. The results provided in this book reveal valuable insights into improving the design and deployment of future WPCNs in the upcoming IoT environment.
This textbook targets advanced-level students studying wireless communications and research engineers working in this field. Industry engineers in mobile device and network development business with an interest in WPCNs and IoT, as well as their PLS solutions, will also find this book useful.

這本教科書介紹了無線供電通信網路（Wireless Powered Communication Networks, WPCNs），作為克服傳統無線通信網路以及新興物聯網網路所面臨的能源瓶頸的有前景的範式。它選擇性地涵蓋了WPCNs中的基本方面，包括無線能量傳輸（Wireless Energy Transfer, WEH）技術、射頻（Radio Frequency, RF）能量收集接收器模型、同時無線信息與能量傳輸（Simultaneous Wireless Information and Power Transfer, SWIPT），以及使用相同波形進行信息和能量聯合傳輸所產生的速率-能量權衡。它涵蓋了WPCNs的網路模型，包括基線和雙跳WPCN模型以及各種相關擴展。本書進一步檢視了在WPCNs的完美運作中必須考慮的關鍵因素，包括吞吐量、公平性和安全性。新的物聯網應用被視為這些因素中的一個關鍵元素。本書還將包含練習題和範例，以及它們的PLS解答。
這是第一本從物理層安全（Physical Layer Security, PLS）角度檢視當前研究的教科書，提供無線能量傳輸（Wireless Power Transfer, WPT）和WPCNs中的信息傳輸的統一視角。本書專注於設計高效的安全傳輸方案、分析能量演變過程，以及在不同的通道狀態信息（Channel State Information, CSI）下評估保密中斷性能，所呈現的結果闡明了如何在無線通信網路中謹慎使用收集的能量，以最佳平衡安全性和吞吐量。本書還通過介紹WPT的背景來概述WPCNs，隨後總結了該領域的研究。作者描述了WPCNs中的物理層安全（PLS）問題，包括該問題的原因及其對WPCNs性能的影響。作者通過介紹WPCNs在物聯網中的應用來擴展討論。
從物聯網（Internet of Things, IoT）的角度來看，這本教科書回顧了最近出現的WPCN無縫整合進入物聯網生態系統的機會和挑戰。它特別針對雙跳WPCN中的上行和下行總吞吐量的最大化問題，同時將WPCN用戶之間的公平性作為約束。本書提供的結果揭示了改善未來WPCNs在即將到來的物聯網環境中設計和部署的寶貴見解。
這本教科書的目標讀者是學習無線通信的高級學生和在該領域工作的研究工程師。對WPCNs和物聯網及其PLS解決方案感興趣的移動設備和網路開發行業工程師也會發現這本書非常有用。
