Available in PDF, EPUB and Kindle. Book excerpt: The conventional design of wireless networks is based on a centralized architecture where a base station, or an access point, directly exchanges data with the end users, and communication is restricted to the one-to-many (broadcast) and many-to-one (multiple-access) single-hop paradigms. However, as the number of users and the data demand increase dramatically, and we move towards the future of wireless networks, multi-hop and multi-flow paradigms are expected to play a central role by enabling a denser spatial reuse of the spectrum and the adaptation to heterogeneous network scenarios characterized by the presence of low-power nodes, relays, and user-operated infrastructure. A major challenge in multi-hop multi-flow wireless networks is that "interference management" and "relaying" are coupled with each other. In other words, wireless relay nodes must play a dual role: they serve as intermediate steps for multi-hop communication and as part of the mechanism that allows interference management schemes. Nonetheless, in the information theory literature, these two tasks have traditionally been addressed separately, and the fundamental principles of the "networks of the future" are currently not well understood. In this dissertation, we take a unified approach to relaying and interference management, and seek to develop tools to study the fundamentals of multi-hop multi-flow wireless networks. In the first part of the dissertation, we study multi-hop multi-flow wireless networks from a high-SNR, or degrees-of-freedom (DoF) perspective. We first consider multi-hop two-unicast networks, and characterize the DoF as a function of the network graph. Then, we consider K x K x K wireless networks and introduce a coding scheme called Aligned Network Diagonalization (AND) that allows the relays to neutralize all the interference experienced by the destinations. This proves that K x K x K wireless networks have K DoF and demonstrates the potential of a coupled approach to relaying and interference management. In the second part of the dissertation, we present a characterization of the Gaussian noise as the worst-case additive noise in multi-hop multi-flow wireless networks. Besides generalizing a classical point-to-point information theory result, this provides theoretical support for the widespread adoption of Gaussian noise models and yields a tool for obtaining capacity outer bounds for Gaussian networks by considering networks with different noise statistics. In the final part of the dissertation, we introduce new techniques to obtain capacity outer bounds for multi-hop multi-flow networks. First, we use the worst-case noise result to show that the capacity region of K xK xK wireless networks with general connectivity can be outer-bounded by the capacity region of the same network under the truncated deterministic model. We then present a generalization of the classical cut-set bound for multi-hop multi-flow deterministic networks, which, besides recovering and unifying other previously known bounds, yields new applications, in both deterministic and non-deterministic settings. In particular, we obtain a rank-based bound for the capacity of linear deterministic multi-flow networks and for the DoF of AWGN multi-flow networks, which yields graph-theoretic conditions for K DoF to be achievable in K x K x K networks with general connectivity.

Book excerpt: Multi-hop communication paradigms are expected to play a central role in future wireless networks by enabling a higher spatial reuse of the spectrum.

Download or read book Real time Communication Protocols for Multi hop Ad hoc Networks written by Reinhard Gotzhein and published by Springer Nature. This book was released on 2020-01-01 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on core functionalities for wireless real-time multi-hop networking with TDMA (time-division multiple access) and their integration into a flexible, versatile, fully operational, self-contained communication system. The use of wireless real-time communication technologies for the flexible networking of sensors, actuators, and controllers is a crucial building block for future production and control systems. WirelessHART and ISA 100.11a, two technologies that have been developed predominantly for industrial use, are currently available. However, a closer analysis of these approaches reveals certain deficits. Current research on wireless real-time communication systems shows potential to remove these limitations, resulting in flexible, versatile, and robust solutions that can be implemented on today’s low-cost and resource-constrained hardware platforms. Unlike other books on wireless communication, this book presents protocols located on MAC layer and above, and build on the physical (PHY) layer of standard wireless communication technologies.

Available in PDF, EPUB and Kindle. Book excerpt: "Wireless communications is one of the most important modern technologies and is interwoven with all aspects of our daily lives. When we wake up, we check social media, email, and news on our smartphones. Before getting up, we adjust the room temperature through a Bluetooth-connected thermostat. After we leave the house and activate the Wi-Fi security cameras, we order a rideshare on a phone app that recognizes our location and are driven to a factory where manufacturing robots are connected and controlled via 5G. And that is only the start of the day.... It is thus no wonder that wireless infrastructure, user devices, and networks are among the largest and most critical industries in most countries. As the demands for wireless services constantly increase, so are the requirements for new products, and for engineers that can develop these products and bring them to market. Such engineers need a deep understanding of both the fundamentals that govern the behavior of wireless systems, the current standardized systems implementations, and more recent research developments that will influence the next generation of products. The goal of this book is to help students, researchers, and practicing engineers to acquire, refresh, or update this knowledge. It is designed to lead them from the fundamental principles and building blocks, such as digital modulation, fading, and reuse of spectrum, to more advanced technologies that underly modern wireless systems, such as multicarrier and multiantenna transmission, to a description of the standardized systems dominating 5G cellular, Wi-Fi, and short-range communications, to the cutting-edge research that will form the basis for beyond-5G systems. In brief, the book leads the reader from the fundamentals to beyond 5G"--

Available in PDF, EPUB and Kindle. Book excerpt: Ad hoc and ubiquitous computing technologies have received extensive attention in both the academia and industry with the explosive growth of wireless communication devices. These technologies are beneficial for many applications, such as offering futuristic high bandwidth access for users, and are expected to offer more exciting and efficient services, anytime and anywhere. In order to satisfy these diverse applications, the design issues of various wireless networks such as ad hoc, sensor, and mesh networks are extremely complicated and there are a number of technique challenges that need to be explored, involving every layer of the OSI protocol stack. This book aims to provide a complete understanding of these networks by investigating the evolution of ad hoc, sensor, and mesh networking technologies from theoretic concept to implementation protocols, from fundamentals to real applications. It provides the necessary background material needed to go deeper into the subject and explore the research literature. The explanation in the book is therefore sufficiently detailed to serve as a comprehensive reference for students, instructors, researchers, engineers, and other professionals, building their understanding of these networks.
