Book Synopsis Fundamentals of Internet of Things for Non-Engineers by : Rebecca Lee Hammons
Download or read book Fundamentals of Internet of Things for Non-Engineers written by Rebecca Lee Hammons and published by CRC Press. This book was released on 2019-06-07 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IoT is the next manifestation of the Internet. The trend started by connecting computers to computers, progressed to connecting people to people, and is now moving to connect everything to everything. The movement started like a race—with a lot of fanfare, excitement, and cheering. We’re now into the work phase, and we have to figure out how to make the dream come true. The IoT will have many faces and involve many fields as it progresses. It will involve technology, design, security, legal policy, business, artificial intelligence, design, Big Data, and forensics; about any field that exists now. This is the reason for this book. There are books in each one of these fields, but the focus was always "an inch wide and a mile deep." There’s a need for a book that will introduce the IoT to non-engineers and allow them to dream of the possibilities and explore the work venues in this area. The book had to be "a mile wide and a few inches deep." The editors met this goal by engaging experts from a number of fields and asking them to come together to create an introductory IoT book. Fundamentals of Internet of Things for Non-Engineers Provides a comprehensive view of the current fundamentals and the anticipated future trends in the realm of Internet of Things from a practitioner’s point of view Brings together a variety of voices with subject matter expertise in these diverse topical areas to provide leaders, students, and lay persons with a fresh worldview of the Internet of Things and the background to succeed in related technology decision-making Enhances the reader’s experience through a review of actual applications of Internet of Things end points and devices to solve business and civic problems along with notes on lessons learned Prepares readers to embrace the Internet of Things era and address complex business, social, operational, educational, and personal systems integration questions and opportunities
Book Synopsis Performance and Security Enhancements of Wireless Networks Through Visible Light and Inaudible Sound by : Pengfei Hu
Download or read book Performance and Security Enhancements of Wireless Networks Through Visible Light and Inaudible Sound written by Pengfei Hu and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless Communication has gone through several paradigm shifts starting from the smoke and torch signal (pre-industry age), to the discovery of electromagnetic waves and the invention of the radio system. In modern day wireless communication systems, the most popular communication media is the Radio Frequency (RF) electromagnetic wave (such as WiFi, LTE, etc.) as it can enable long-distance and rapid transmission with better quality and smaller, cheaper devices. However, there are some limitations of the RF technology. First, the shortage of RF spectrum in the wireless communication has been identified along with the exponential increase of the mobile wireless data traffic in the past two decades. The current RF spectrum is scarce to meet the ever-increasing traffic demand even with the efficient frequency and spatial reuse. The strict regulation of RF spectrum clearly constrains the RF based wireless system in terms of flexibility in allocating spectrum resources, which makes the situation even worse. Second, due to the long wavelength of RF, it can easily penetrate through most objects and walls. This inherent characteristic of RF leads to the severe interference among multiple transceivers and the vulnerability to eavesdropping attacks. Third, many kinds of mobile application cannot be achieved solely with RF, such as fine-granularity indoor localization, proximity detection, etc. To overcome the aforementioned constraints of the RF-only wireless network, our research focuses on improving the performance and enhancing the security of wireless network through alternative transmission medium -- visible light and inaudible sound. In this thesis, we discuss three systems which either utilizes the visible light or inaudible sound to provide better services for mobile devices. In the first work, we present ColorBars, a Visible Light Communication system that utilizes Color Shift Keying (CSK) to modulate the data using different colors transmitted by the LED. It exploits the increasing popularity of Tri-LEDs (RGB) that can emit a wide range of colors. We show that commodity cameras can efficiently and accurately demodulate the color symbols. ColorBars ensures the flicker-free and reliable communication even in the presence of inter-frame loss and diversity of rolling shutter cameras. In the second work PCASA, we utilize the acoustic communication for secure proximity estimation with sub-meter level accuracy. PCASA uses Differential Pulse Position Modulation scheme that modulates data through varying the silence period between acoustic pulses to ensure the energy efficiency even when the authentication operation is being performed once every second. To augment the existing WiFi network, we propose PLiFi, a hybrid WiFi-VLC network architecture through the use of Power Line Communication (PLC). PLiFi creates a high-speed interconnection between LEDs themselves and Internet at low cost, and also seamlessly integrates WiFi and VLC networks. With the alternative transmission medium, we could (1) relieve the overcrowded Radio Frequency spectrum imposed by the evergrowing interconnection demand of smart devices and IoT, (2) provide some novel services which are difficult to achieve by the RF-only wireless communication, such as visual association, fine-grained location specific advertisement, etc., (3) ease the inherent security vulnerability of RF.

Book Synopsis The Internet of Materials by : Christos Liaskos
Download or read book The Internet of Materials written by Christos Liaskos and published by CRC Press. This book was released on 2020-12-03 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: State-of-the-art, flat structures called metasurfaces can filter and steer light and sound, render an object completely invisible to electromagnetic waves, and much more. They can deliver automation, remote operation, and advanced performance to a wide variety of existing systems, with applications in communications, medical imaging, sensing, and security. However, for non-specialists, individual metasurfaces are currently restricted to limited reusability and accessibility. This book brings together various scientific disciplines with the aim of outlining a programmable ‘plug-and-play’ metasurface. The book focuses on a recently proposed platform – known as the HyperSurface – that provides many electromagnetic functions of metasurfaces in a single structure, which can be controlled and reconfigured by software. This revolutionary approach paves the way for new opportunities in wireless communications and programmable wireless environments: HyperSurfaces could link networks with objects and physical environments and create smarter systems that are far more responsive to user demands. Walls that absorb radiation or block digital eavesdropping, and wireless, long-distance charging of devices are among the many possibilities. The book aspires to provide the foundational knowledge for creating an Internet of Materials, enabling smart environments at any scale – from indoor wireless communications to medical imaging equipment. Although the set of disciplines involved covers a considerable span, we hope that the material will benefit experts and students alike.
