Available in PDF, EPUB and Kindle. Book excerpt: The emergence of the massive Internet-of-things (IoT) market, i.e., applications with large-scale deployment of Internet-enabled devices, is transforming many sectors, including cities, logistics, retail, and agriculture. Nevertheless, a large-scale uptake of such applications is intertwined with connectivity challenges due to the unique traffic characteristics of massive IoT and the high density of IoT devices. The main objective of this dissertation is to develop spectrum sharing solutions to enable massive IoT connectivity over the unlicensed and licensed bands. To this end, we unravel the interplay between the intra-network sharing and inter-network sharing, i.e., how a high density of low-cost IoT devices should share the spectrum among themselves while still harmoniously coexist with other wireless networks. We first present a framework to model and analyze ultra-narrowband (UNB) communications, where IoT devices randomly access the unlicensed spectrum using extremely narrowband signals. The framework enables tractable analysis of large-scale networks, identifying fundamental limits and proposing enhancements that help UNB networks support a higher density of low-rate IoT devices. We then present an access scheme that supports applications with higher rates over unlicensed bands with sensing regulations. To this end, we revisit spectrum sensing for massive IoT and propose a sensing-based system, where base stations with narrowband receivers locally share and process sensing reports to scan a wideband spectrum, identifying resources at a fine spectral resolution and aggressively reusing them over space. Next, for applications with strict quality-of-service guarantees, we consider cellular connectivity, where we develop a shared spectrum access protocol, leveraging drones as IoT data aggregators. The proposed protocol maximizes the energy-efficiency of IoT devices while still protecting existing cellular users from interference. Last, we analyze and optimize the densification of small cells to maximize coverage and rate of users and IoT devices. To deliver these contributions, we leverage tools from stochastic geometry, communication theory, and optimization, working across the theoretical analysis and practical algorithm development. We validate the effectiveness of the proposed solutions via comprehensive simulations of wide-area networks. We glean several design guidelines and recommendations throughout the dissertation, which can be of relevance to wireless communications engineers, network operators, and standard bodies.

Download or read book AI enabled Spectrum Sharing written by Lin Zhang and published by Springer. This book was released on 2024-10-18 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless edge networks aim to provide last-mile wireless connections between access points and diversified wireless end devices. Recent years witness the rapid development of wireless communication ecosystems including fundamental theory breakthroughs, manufacture capability improvements, as well as the explosively increasing wireless end devices and service demands. It is known that spectrum is the irreplaceable resource for wireless transmissions in edge networks. Nevertheless, it is quite challenging and inefficient to allocate dedicated spectrum for each single transmission link due to the severe shortage of spectrum resource. Alternatively, by enabling different links to use the same spectrum, spectrum sharing is envisioned to be a promising paradigm to properly accommodate the conflict between the scarce spectrum resource and substantial spectrum demands. Conventionally, model-driven optimization methods are widely adopted to optimize the spectrum sharing policy in the edge network and achieve friendly coexistence among different transmission links. However, future wireless edge network is predicted to be large-scale and heterogeneous, model-driven optimization methods will be problematic such as imperfect modelling and unacceptable overheads. Different from the existing related books on spectrum sharing or spectrum management for wireless edge networks, our book leverages the artificial intelligence (AI) to achieve smart spectrum sharing for wireless edge networks and elaborates AI-enabled spectrum sharing technique in typical scenarios, which can guide the development of next-generation spectrum sharing standards, as well as provide innovative spectrum sharing methods for related practitioners, including research fellow, lecturers, and students.

Download or read book Internet of Things and the Law written by Guido Noto La Diega and published by Taylor & Francis. This book was released on 2022-10-14 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Internet of Things and the Law: Legal Strategies for Consumer-Centric Smart Technologies is the most comprehensive and up-to-date analysis of the legal issues in the Internet of Things (IoT). For decades, the decreasing importance of tangible wealth and power – and the increasing significance of their disembodied counterparts – has been the subject of much legal research. For some time now, legal scholars have grappled with how laws drafted for tangible property and predigital ‘offline’ technologies can cope with dematerialisation, digitalisation, and the internet. As dematerialisation continues, this book aims to illuminate the opposite movement: rematerialisation, namely, the return of data, knowledge, and power within a physical ‘smart’ world. This development frames the book’s central question: can the law steer rematerialisation in a human-centric and socially just direction? To answer it, the book focuses on the IoT, the sociotechnological phenomenon that is primarily responsible for this shift. After a thorough analysis of how existing laws can be interpreted to empower IoT end users, Noto La Diega leaves us with the fundamental question of what happens when the law fails us and concludes with a call for collective resistance against ‘smart’ capitalism.
