This book is based on the basic principles of physics (including electromagnetics, optics, thermodynamics, etc.), with engineering mathematical methods as the core of detection and control algorithm design. Furthermore, this book innovatively applies semi-physical verification and detection technology to the dynamic performance testing of radio-frequency identification (RFID) systems. This book proposes a series of new theories and methods for physical collision prevention, as well as related test verification methods for building semi-physical hardware platforms based on photoelectric sensing technology, which will provide important theories and technical supports for the applications of the internet of things (IoT) systems in smart logistics, car networking, food traceability, anti-counterfeiting, and other livelihood fields. The main contributions of this book are as follows:(1) It introduces a new theory of physical anti-collision for improving the integral performance of multi-tag RFID systems.(2) It studies the principles and optimization algorithms of innovative multi-tag network topologies, which enhance the sensing capability of the RFID system. (3) It provides valuable guidance for RFID system physical anti-collision based on deep learning. (4) It combines physical and electrical expertise from an interdisciplinary standpoint toward the analysis and design of dynamic performance testing systems.
RFID Collision Problem and Research Progress of Anti-CollisionInternet of things (IoT) as a new technology has developed rapidly in recent years, which is an important part of a new generation of information systems. The emergence of IoT is another information technology revolution after computers, the Internet, and mobile communications [1]. As one of the core technologies in the field of perception of IoT, radio-frequency identification (RFID) technology is a
