RFID Technologies for Internet of Things

Más información sobre el libro

This book explores RFID applications within the Internet of Things, focusing on emerging technologies for tag search, anonymous RFID authentication, and networked tag identification. It introduces a new technique called filtering vector, a compact data structure that encodes tag IDs, enabling efficient tag filtration to meet real-world delay requirements. A novel iterative tag search protocol is also designed, enhancing search accuracy and reducing iteration time by leveraging information from previous attempts. This protocol is adaptable to noisy channels. The authors shift the traditional approach to anonymous RFID authentication by adopting an asymmetry design principle, which simplifies tags while increasing complexity for readers. A technique for dynamically generating random tokens for authentication is introduced, resulting in minimal communication and computation overhead per authentication for both readers and tags. The book addresses networked-tag identification, criticizing traditional contention-based protocols for their high energy costs in multihop systems. Instead, a reader-coordinated design that serializes tag transmissions is proposed, along with a serial number-based solution for load balancing to reduce energy costs. Aimed at researchers and professionals, this SpringerBrief will also benefit advanced-level students focused on network design, particularly in efficiency, security, and privacy.
