Sensing Using Ubiquitous Wireless Communication Infrastructure available in PDF, EPUB and Kindle. 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.

Principles and Applications of Ubiquitous Sensing available in PDF, EPUB and Kindle. Applications which use wireless sensors are increasing in number. The emergence of wireless sensor networks has also motivated the integration of a large number of small and lightweight nodes which integrate sensors, processors, and wireless transceivers. Existing books on wireless sensor networks mainly focus on protocols and networks and pay little attention to the sensors themselves which the author believes is the main focus. Without adequate knowledge of sensors as well as how they can be designed, realized and used, books on wireless sensor networks become too theoretical and irrelevant. The purpose of this book is to intimately acquaint readers with the technique of sensing (resistive, capacitive, inductive, magnetic, inertial, etc.) and existing sensor technologies. It also discusses how the sensors are used in a wide application domain and how new sensors can be designed and used in a novel way.

Download and read online ebook Cooperating Embedded Systems and Wireless Sensor Networks write by Michel Banatre. This book was released on 2010-01-05. Cooperating Embedded Systems and Wireless Sensor Networks available in PDF, EPUB and Kindle. A number of different system concepts have become apparent in the broader context of embedded systems over the past few years. Whilst there are some differences between these, this book argues that in fact there is much they share in common, particularly the important notions of control, heterogenity, wireless communication, dynamics/ad hoc nature and cost. The first part of the book covers cooperating object applications and the currently available application scenarios, such as control and automation, healthcare, and security and surveillance. The second part discusses paradigms for algorithms and interactions. The third part covers various types of vertical system functions, including data aggregation, resource management and time synchronization. The fourth part outlines system architecture and programming models, outlining all currently available architectural models and middleware approaches that can be used to abstract the complexity of cooperating object technology. Finally, the book concludes with a discussion of the trends guiding current research and gives suggestions as to possible future developments and how various shortcomings in the technology can be overcome.

Pervasive Computing available in PDF, EPUB and Kindle. nd Welcome to the proceedings of PERVASIVE 2004, the 2 International C- ference on Pervasive Computing and the premier forum for the presentation and appraisal of the most recent and most advanced research results in all - undational and applied areas of pervasive and ubiquitous computing. Consi- ring the half-life period of technologies and knowledge this community is facing, PERVASIVE is one of the most vibrant, dynamic, and evolutionary among the computer-science-related symposia and conferences. The research challenges, e?orts, and contributions in pervasive computing have experienced a breathtaking acceleration over the past couple of years, mostly due to technological progress, growth, and a shift of paradigms in c- puter science in general. As for technological advances, a vast manifold of tiny, embedded, and autonomous computing and communication systems have st- ted to create and populate a pervasive and ubiquitous computing landscape, characterized by paradigms like autonomy, context-awareness, spontaneous - teraction, seamless integration, self-organization, ad hoc networking, invisible services, smart artifacts, and everywhere interfaces. The maturing of wireless networking, miniaturized information-processing possibilities induced by novel microprocessor technologies, low-power storage systems, smart materials, and technologies for motors, controllers, sensors, and actuators envision a future computing scenario in which almost every object in our everyday environment will be equipped with embedded processors, wireless communication facilities, and embedded software to perceive, perform, and control a multitude of tasks and functions.
