    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 scenariosand 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.

  • - A Crowdsourcing Approach
    von Chenshu Wu
    94,00 €

    This book provides a comprehensive and in-depth understanding of wireless indoor localization for ubiquitous applications. The past decade has witnessed a flourishing of WiFi-based indoor localization, which has become one of the most popular localization solutions and has attracted considerable attention from both the academic and industrial communities. Specifically focusing on WiFi fingerprint based localization via crowdsourcing, the book follows a top-down approach and explores the three most important aspects of wireless indoor localization: deployment, maintenance, and service accuracy. After extensively reviewing the state-of-the-art literature, it highlights the latest advances in crowdsourcing-enabled WiFi localization. It elaborated the ideas, methods and systems for implementing the crowdsourcing approach for fingerprint-based localization. By tackling the problems such as: deployment costs of fingerprint database construction, maintenance overhead of fingerprint database updating, floor plan generation, and location errors, the book offers a valuable reference guide for technicians and practitioners in the field of location-based services. As the first of its kind, introducing readers to WiFi-based localization from a crowdsourcing perspective, it will greatly benefit and appeal to scientists and researchers in mobile and ubiquitous computing and related areas.
