Pervasive Ambient Communication for Internet of Things

This book covers several essential aspects of pervasive ambient backscatter communication, one of the most cutting-edge technologies for Internet-of-Things. It begins with introductory Part I, which presents visions, basic concepts, principles, and paradigms of ambient backscatter. Also, a taxonomy of state-of-the-art ambient backscatter systems is provided from the perspective of the OSI model. Part II and III study how ambient backscatter systems work on the communication and networking levels. Specifically, Part II discusses in detail how to make use of ambient WiFi signals to provide high-throughput backscatter communications with WiFi 1 (chapter 5), WiFi 2-3 (chapter 4), WiFi 4 (chapter 3), WiFi 5-6 (chapter 6) standards. Further, Part III includes several of the most advanced ambient backscatter network solutions, which are made possible by the first multi-hop backscatter (chapter 7), first backscatter mesh (chapter 8), and multiprotocol backscatter (chapter 9). On top of reliable communication and networks, we propose two novel applications that are thought impossible before, lightweight spatial sound recording over the air (chapter 10) and self-powered wireless wearables for healthcare (chapter 11). To conclude the monograph, we point out critical challenges for realizing the vision of pervasive backscatter IoTs and potential directions of ambient backscatter applications.
The book provides an in-depth understanding of ambient backscatter technologies. In particular, we mainly take ubiquitous WiF signals as the communication sources and adopt a top-down approach to introduce three crucial subjects: WiFi backscatter communication, ambient backscatter network, and self-powered application systems. For each subject, we carefully divide it into several relatively independent topics, which come with the latest advances in pervasive backscatter and include extensive discussions of closely related state-of-the-art methodologies.

這本書涵蓋了普遍環境背散射通訊的幾個重要方面，這是物聯網中最尖端的技術之一。它以介紹性的第一部分開始，介紹了環境背散射的願景、基本概念、原則和範式。此外，從OSI模型的角度提供了一個最新的環境背散射系統分類。第二部分和第三部分研究了環境背散射系統在通訊和網絡層面上的工作原理。具體而言，第二部分詳細討論了如何利用環境WiFi信號提供具有WiFi 1 (第5章)、WiFi 2-3 (第4章)、WiFi 4 (第3章)、WiFi 5-6 (第6章)標準的高吞吐量背散射通訊。此外，第三部分包括了幾個最先進的環境背散射網絡解決方案，這些解決方案是由第一個多跳背散射 (第7章)、第一個背散射網絡 (第8章)和多協議背散射 (第9章)實現的。除了可靠的通訊和網絡，我們提出了兩個之前被認為是不可能的新應用，即空中輕量級空間聲音錄製 (第10章)和自供電的醫療無線可穿戴設備 (第11章)。總結這本專著，我們指出了實現普遍背散射物聯網願景的關鍵挑戰和環境背散射應用的潛在方向。
這本書提供了對環境背散射技術的深入理解。特別是，我們主要以無所不在的WiFi信號作為通訊來源，並採用自上而下的方法介紹了三個關鍵主題：WiFi背散射通訊、環境背散射網絡和自供電應用系統。對於每個主題，我們仔細將其分為幾個相對獨立的主題，並包含了普遍背散射的最新進展，並對相關的最新方法進行了廣泛的討論。
