Available in PDF, EPUB and Kindle. Book excerpt: Many applications in the emerging smart environments, such as smart cities and intelligent transportation, require an accurate situational awareness, i.e., information about presence and location of all users in the environment. A reliable situational awareness is based on robust communications and sensing techniques, as well as large-scale deployment. Therefore, an integration of sensing functionality is envisioned as a native capability of next generation wireless networks. This work provides a novel radio sensing approach for the localization of non-cooperative users, referred to as multipath-enhanced device-free localization (MDFL). For localization, MDFL exploits user-induced variations in the received power of static signal components, i.e., line-of-sight and multipath components. Due to its low computational complexity, the proposed MDFL approach represents a suitable technique for the emerging perceptive wireless networks and can help to enable ubiquitous radio sensing.
Download or read book Sensing Using Ubiquitous Wireless Communication Infrastructure written by Kiran Raj Joshi and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An estimated 12 billion connected devices exist today and this number is expected to grow to 30 billion by 2020. These connected devices will be used to control everyday objects like thermostat, light bulb, or even our coffee machines. Sensors and network connectivity are two very important enablers for these devices. Most of these devices will be connected via ubiquitous wireless networks like WiFi, Bluetooth, and ZigBee. Despite their widespread deployment, these wireless networks so far have been used solely for the purpose of transferring digital data between radios. In this thesis, we will describe how we can overload functionalities to these ubiquitous wireless networks by adding novel sensing modalities into them. We first describe the design and implementation of a localization system that can pinpoint radios to sub-meter accuracy in an indoor environment. This system provides localization by simply analyzing the wireless signal that is used for communication. Such a localization system can help network managers to identify and locate unauthorized interferers. At the same time, such a localization technique can also enable navigation of large indoor spaces like airports and malls using smartphones. Next, we describe a technique that allows a wireless Access Point (AP) to detect and analyze reflections of wireless signal from its own transmission. In particular, we demonstrate how it enables a WiFi AP to trace human motion by simply listening to and analyzing reflections from its own transmission. But this technique also has many more applications beyond motion tracing. As an example, we describe design and implementation of a system which allows us to passively read data from Internet of Things (IoT) sensors using ambient WiFi signals. Such a system can prolong life of battery operated sensors or even pave path for RF powered sensors in the future.

Book excerpt: 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.

Download or read book Location Systems written by Anthony LaMarca and published by Morgan & Claypool Publishers. This book was released on 2008-07-08 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in electronic location technology and the coming of age of mobile computing have opened the door for location-aware applications to permeate all aspects of everyday life. Location is at the core of a large number of high-value applications ranging from the life-and-death context of emergency response to serendipitous social meet-ups. For example, the market for GPS products and services alone is expected to grow to US$200 billion by 2015. Unfortunately, there is no single location technology that is good for every situation and exhibits high accuracy, low cost, and universal coverage. In fact, high accuracy and good coverage seldom coexist, and when they do, it comes at an extreme cost. Instead, the modern localization landscape is a kaleidoscope of location systems based on a multitude of different technologies including satellite, mobile telephony, 802.11, ultrasound, and infrared among others. This lecture introduces researchers and developers to the most popular technologies and systems for location estimation and the challenges and opportunities that accompany their use. For each technology, we discuss the history of its development, the various systems that are based on it, and their trade-offs and their effects on cost and performance. We also describe technology-independent algorithms that are commonly used to smooth streams of location estimates and improve the accuracy of object tracking. Finally, we provide an overview of the wide variety of application domains where location plays a key role, and discuss opportunities and new technologies on the horizon.

Book excerpt: Thisvolumehasitsbeginningsinalaboratoryproject,developmentofaradiolocator for the Wi-Fi network that was growing by leaps and bounds on the campus of Indiana University at that time. What started as a very focused and practical attempt to improve network management, touched in its lifetime upon broader issues of the use of radio spectrum, design of system architectures for the wireless medium, and image formation outside the limits of geometrical optics. Ihaveintendedthisbookmostlyfortheaudienceofengineersandsystemdesi- ers, in the growing ?eld of radio communication among small, portable, ubiquitous devices that have become hybrid platforms for personal communication and p- sonal computing. It is also a book addressed to network professionals, people to whom radio is largely a black box, a medium that they usually rely upon, but s- dom fully understand. In fact, in the course of my work in the ?eld, I have witnessed, to my dismay, a wide disconnect between the networking world and the radio technology that n- working has come to depend upon so heavily. Perhaps, because digital wireless communication is seen as digital ?rst and wireless second, there is often a m- placed emphasis on its information-processingside, with the methodologycentered around the discrete symbol, and with little intuition of the underlying physics. I had it once suggested to me, in apparent seriousness, to use radio cards for intra-system communication within a radiolocator! Wireless communication is radio, plain and simple.

Available in PDF, EPUB and Kindle. Book excerpt: "...a must-read text that provides a historical lens to see how ubicomp has matured into a multidisciplinary endeavor. It will be an essential reference to researchers and those who want to learn more about this evolving field." -From the Foreword, Professor Gregory D. Abowd, Georgia Institute of Technology First introduced two decades ago, the term ubiquitous computing is now part of the common vernacular. Ubicomp, as it is commonly called, has grown not just quickly but broadly so as to encompass a wealth of concepts and technology that serves any number of purposes across all of human endeavor. While such growth is positive, the newest generation of ubicomp practitioners and researchers, isolated to specific tasks, are in danger of losing their sense of history and the broader perspective that has been so essential to the field’s creativity and brilliance. Under the guidance of John Krumm, an original ubicomp pioneer, Ubiquitous Computing Fundamentals brings together eleven ubiquitous computing trailblazers who each report on his or her area of expertise. Starting with a historical introduction, the book moves on to summarize a number of self-contained topics. Taking a decidedly human perspective, the book includes discussion on how to observe people in their natural environments and evaluate the critical points where ubiquitous computing technologies can improve their lives. Among a range of topics this book examines: How to build an infrastructure that supports ubiquitous computing applications Privacy protection in systems that connect personal devices and personal information Moving from the graphical to the ubiquitous computing user interface Techniques that are revolutionizing the way we determine a person’s location and understand other sensor measurements While we needn’t become expert in every sub-discipline of ubicomp, it is necessary that we appreciate all the perspectives that make up the field and understand how our work can influence and be influenced by those perspectives. This is important, if we are to encourage future generations to be as successfully innovative as the field’s originators.
