What is at stake socially, culturally, politically, and economically when we routinely use technology to gather information about our bodies and environments? Today anyone can purchase technology that can track, quantify, and measure the body and its environment. Wearable or portable sensors detect heart rates, glucose levels, steps taken, water quality, genomes, and microbiomes, and turn them into electronic data. Is this phenomenon empowering, or a new form of social control? Who volunteers to enumerate bodily experiences, and who is forced to do so? Who interprets the resulting data? How does all this affect the relationship between medical practice and self care, between scientific and lay knowledge? Quantified examines these and other issues that arise when biosensing technologies become part of everyday life. The book offers a range of perspectives, with views from the social sciences, cultural studies, journalism, industry, and the nonprofit world. The contributors consider data, personhood, and the urge to self-quantify; legal, commercial, and medical issues, including privacy, the outsourcing of medical advice, and self-tracking as a "paraclinical" practice; and technical concerns, including interoperability, sociotechnical calibration, alternative views of data, and new space for design. Contributors Marc Boehlen, Geoffrey C. Bowker, Sophie Day, Anna de Paula Hanika, Deborah Estrin, Brittany Fiore-Gartland, Dana Greenfield, Judith Gregory, Mette Kragh-Furbo, Celia Lury, Adrian Mackenzie, Rajiv Mehta, Maggie Mort, Dawn Nafus, Gina Neff, Helen Nissenbaum, Heather Patterson, Celia Roberts, Jamie Sherman, Alex Taylor, Gary Wolf
In multi-hop wireless networks; that is, networks where messages must traverse multiple nodes before reaching their destination, wireless relay nodes must play a dual role: they serve as intermediate steps for relaying schemes and as part of the mechanism that allows interference management schemes. Hence, relaying and interference management are two key aspects of communication in wireless networks. Both these aspects are introduced in a tutorial manner before going on to consider the combination of the two. In multi-hop multi-flow networks, the challenge is to combine the insights obtained in the study of single-hop multi-flow networks and multi-hop single-flow networks in order to design schemes that handle relaying and interference management simultaneously. This monograph discusses the gains that can be obtained by taking such a unified approach to relaying and interference management. Multihop Wireless Networks is of interest to students and researchers working on modern network systems.
This monograph provides a tutorial on a family of sequential learning and decision problems known as the multi-armed bandit problems. In such problems, any decision serves the purpose of exploring or exploiting or both. This balancing act between exploration and exploitation is characteristic of this type of ""learning-on-the-go"" problem, in which we have to instantaneously apply what we have learned so far, even as we continue to learn. The authors give an in-depth introduction to the technical aspects of the theory of decision-making technologies. The range is comprehensive and covers topics that have applications in many networking systems. These include Recommender systems, Ad Placement systems, the smart grid, and clinical trials. Online Learning Methods for Networking is essential reading for students working in networking and machine learning. Designers of many network-based systems will find it a valuable resource for improving their technology.
Just as the steam engine was the driving force behind the Industrial Revolution, today, broadband Internet is seen as critical to the transition of knowledge-intensive economies across the world. As a general purpose technology, broadband Internet is considered a fundamental driver of economic growth and social development, releasing the innovative potential and energy of previously disenfranchised members of the population. Many of the countries in the Middle East and North Africa region (MENA) now recognize that broadband Internet is crucial to their efforts to reduce poverty and create job opportunities, especially for their young populations and for women. Broadband Networks in the Middle East and North Africa re-emphasizes the important contribution that broadband Internet can make and assesses the status of existing nfrastructure in at least 18 MENA countries. While there is significant potential across the region, the take-up of broadband Internet has been slow and the price of broadband service is high in many countries. In large part, this stems from market structures that, too often, reflect the past when telecommunications were treated as a monopoly utility service. The report finds that there are gaps in infrastructure regionally with no connectivity between neighboring countries in some cases. Similarly, there are gaps within countries exacerbating the (digital) divide between rural and urban areas. "Broadband Networks in the Middle East and North Africa" examines the regulatory and market bottlenecks that are hampering the growth of the Internet in these and other MENA countries: the five North African countries (Algeria, Egypt, Morocco, Libya, Tunisia); the six Mashreq countries (the Islamic Republic of Iran, Iraq, Jordan, Lebanon, Syria, and the West Bank and Gaza economy); the six Gulf countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates); and Djibouti and the Republic of Yemen. Last, the report provides policy and regulatory options for increasing effective use of existing fixed and mobile infrastructure as well as alternative infrastructure networks such as power grids and railroads. It explains the benefits of effective cross-sector infrastructure construction frameworks, highlighting the need to adjust market structures to foster competitive behavior among service providers to bring down prices and stimulate the demand for value-added services to drive future broadband development.
Stable Throughput Regions in Wireless Networks examines the fundamentals of stable throughput in wireless networks. It reviews the notion of stability and of stable throughput regions in wireless networks, with emphasis on network layer cooperation between interacting users. After a brief introduction, it examines in detail specific instances of the stability issue. These instances differ from each other in terms of the network, channel and traffic models they use. What they share is the notion of how stability is affected by node cooperation, as well as the notion of ""interacting queues"" that makes the stable throughput analysis difficult and often intractable. This review is intended to provide a reference point for the rich set of network control problems that arise in the context of queue stability in modern and future networks.
It is widely accepted that nanonetworks will enable a plethora of long-awaited applications, ranging from healthcare to homeland security, industrial development and environmental protection. Enabling communication among nanomachines is still a major challenge. While it is acknowledged that there is still a long way to go before having a fully functional nanomachine, this book makes the case that hardware-oriented research and communication-focused investigations will benefit from being conducted in parallel from an early stage. Fundamentals of Electromagnetic Nanonetworks in the Terahertz Band defines the first steps towards enabling electromagnetic communication among nanomachines in the Terahertz Band (0.1-10 THz). The starting point is the development of novel graphene-based plasmonic nano-antennas, which efficiently operate in the Terahertz Band. The authors have developed a novel Terahertz Band channel model and investigated the potential of this frequency band by means of a channel capacity analysis. In light of the channel peculiarities and the nanomachine capabilities, they put forward a set of communication mechanisms for nanonetworks, which include femtosecond-long pulse-based modulations, low-weight channel coding schemes, a new symbol detection scheme at the receiver, and a new medium access control protocol for nanonetworks. In addition, the book analyzes the performance of perpetual nanonetworks by developing a joint energy harvesting and energy consumption model for self-powered nanomachines. Finally, an emulation platform has been developed to simulate a one-to-one nano-link between nanomachines and validate the developed models.

Economic Modeling in Networking: A Primer is designed to provide engineering students who have a basic training in economic modeling and game theory an understanding of where and when game theoretic models are employed, the assumptions underpinning key models, and conceptual insights that are broadly applicable. In recent years, engineers have been increasingly called upon to have basic skills in economic modeling and game theory at their disposal for two related reasons. First, the economics of networks has a significant effect on the adoption and creation of network innovations, and second, engineered networks serve as the platform for many of our most basic economic interactions today. Despite these confluences, the typical engineering student does not garner economic training until later in their graduate career, if at all. This monograph takes the stance that basic economic understanding is a critical tool in the arsenal of the modern engineering student. Economic Modeling in Networking: A Primer is intended to help engineering students to work with economic models but also to cast a critical eye over such models. As such, it is also an ideal complementary text to a good introductory textbook or course on microeconomics or game theory
The weighted sum-rate maximization (WSRMax) problem plays a central role in many network control and optimization methods, such as power control, link scheduling, cross-layer control, network utility maximization. The problem is NP-hard in general. In Weighted Sum-Rate Maximization in Wireless Networks: A Review, a cohesive discussion of the existing solution methods associated with the WSRMax problem, including global, fast local, as well as decentralized methods is presented. In addition, general optimization approaches, such as branch and bound methods, complementary geometric programming, and decomposition methods, are discussed in depth to address the problem. Through a number of numerical examples, the applicability of the resulting algorithms in various application domains is demonstrated. The presented algorithms and the associated numerical results can be very useful for network engineers or researchers with an interest in network design.

Transmission Capacity of Wireless Networks presents a framework for computing the outage probability (OP) and transmission capacity (TC) in a wireless network. Transmission capacity is a performance metric for wireless networks that measures the spatial intensity of successful transmissions per unit area, subject to a constraint on the permissible outage probability (where outage occurs when the SINR at a receiver is below a threshold). This volume gives a unified treatment of the TC framework that has been developed by the authors and their collaborators over the past decade. The mathematical framework underlying the analysis is stochastic geometry: Poisson point processes model the locations of interferers, and (stable) shot noise processes represent the aggregate interference seen at a receiver. Transmission Capacity of Wireless Networks presents TC results (exact, asymptotic, and bounds) on a simple model in order to illustrate a key strength of the framework: analytical tractability yields explicit performance dependence upon key model parameters. It goes on to present enhancements to this basic model - channel fading, variable link distances, and multihop.Chapter 5 presents four network design case studies well-suited to TC: (i) spectrum management, (ii) interference cancellation, (iii) signal threshold transmission scheduling, and iv) power control. Chapter 6 studies the TC when nodes have multiple antennas, which provides a contrast vs. classical results that ignore interference. Transmission Capacity of Wireless Networks is essential reading for anyone with an interest in wireless network design and in understanding the fundamentals of the performance and behavior of such networks.

Pitroda registered his first patent on the mobile wallet in 1994, and since then he and his colleague, Mehul Desai, have been traversing the world, taking this technology forward. Initially resistant to the idea of mobile money, the three stakeholders in mobile telephony - telecom companies, banks and merchants - are now realizing that it is crucial to their growth. All of them are now reinventing themselves for our mobile phones, and competing with each other to manage our lifestyles. For telecom companies, it is no longer about connectivity but about delivering personalized and secure services. For banks, it is no longer about deposits and lending but about the convergence of financial products and services; and for merchants, it is no longer about goods but goods bundled with services. For India, which has more mobile phone subscribers (over 470 million, with over ten million being added every month) than bank account holders, mobile money can be an engine for growth. It can also be a life-transforming technology for social good, empowering those at the bottom of the pyramid. Once again, India can show the way to the world.
Interference is the main performance-limiting factor of large wireless communication systems. To analyze and design these networks, it is thus imperative that the interference is statistically characterized or bounded in the presence of various sources of uncertainty, including the users' positions, their patterns of activity, and the channel fading states. Interference in Large Wireless Networks addresses this problem using basic probability and tools from stochastic geometry. Starting with regular networks and the popular Poisson model, it discusses increasingly more general networks. In addition to the interference itself, it also derives explicit expressions for outage probabilities, which are indispensable for the optimization of higher-level metrics such as the transport capacity or end-to-end delay. The book includes an appendix that reviews the underlying mathematical tools, which makes it self-contained and suitable for graduate students, researchers, and wireless engineers alike.

This volume discusses wireless network modeling and performance analysis with the aim of showing how stochastic geometry can be used in a more or less systematic way to analyze the phenomena that arise in this context. The book first focuses on medium access control mechanisms used in ad hoc networks and in cellular networks. It then discusses the use of stochastic geometry for the quantitative analysis of routing algorithms in mobile ad hoc networks. The appendix also contains a concise summary of wireless communication principles and of the network architectures considered in the two volumes. |
