Cross-Technology Communication for Internet of Things: Fundamentals and Key Technologies

Cross-technology communication (CTC) is a technology that enables direct communication between heterogeneous devices that use different wireless standards. It works like a "translator" between two or more wireless technologies. CTC not only creates a new avenue for inter-operation and data exchange between wireless devices but also enhances the ability to manage wireless networks.

This book focuses on the enabling technology CTC and introduces readers to a variety of CTC techniques in heterogeneous wireless networks. These techniques can be divided into two categories: packet-level CTCs based on energy modulation and channel intervention; and physical-level CTCs based on cross-demapping, digital emulation, and split encoding. The book offers a comprehensive comparison and analysis, granting readers a deeper understanding of CTC techniques in terms of throughput, reliability, hardware modification, and concurrency. Moreover, it highlights upper-layer CTC application scenarios and cutting-edge developments, which include but are not limited to interference management, channel quality estimation, network routing, etc.

The book is intended for all readers - e.g., researchers, students, and even professionals - who are interested in the areas of wireless networking, wireless communication, mobile computing, and Internet of Things. The findings and summaries presented here can help: 1) guide researchers to rethink CTC techniques in connection with design methodology; 2) further advance the infrastructure of future IoT by introducing CTC; and 3) enable important IoT applications by delivering ubiquitous network connectivity.

跨技術通訊（CTC）是一種技術，可以在使用不同無線標準的異質設備之間實現直接通訊。它像是兩個或多個無線技術之間的「翻譯器」。CTC不僅為無線設備之間的互操作和數據交換創造了新的途徑，還增強了管理無線網絡的能力。

本書專注於啟用技術CTC，並向讀者介紹異質無線網絡中的各種CTC技術。這些技術可以分為兩個類別：基於能量調制和通道干預的分組級CTC，以及基於交叉解映射、數字仿真和分割編碼的物理級CTC。本書提供了全面的比較和分析，使讀者更深入地了解CTC技術在吞吐量、可靠性、硬件修改和並發性方面。此外，它還突出了上層CTC應用場景和尖端發展，包括但不限於干擾管理、通道質量估計、網絡路由等。

本書適用於所有讀者，例如研究人員、學生，甚至專業人士，他們對無線網絡、無線通信、移動計算和物聯網等領域感興趣。這裡提供的研究結果和摘要可以幫助：1）引導研究人員重新思考與設計方法融合的CTC技術；2）通過引入CTC進一步推進未來物聯網的基礎設施；3）通過提供無所不在的網絡連接性，實現重要的物聯網應用。
