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.

Encyclopedia on Ad Hoc and Ubiquitous Computing available in PDF, EPUB and Kindle. 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.

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.
