The realization of the ???Internet of Things??????a world in which billions of objects will report their location, identity, and history over wireless connections???will require dramatic changes in systems, architectures, and communications. Although RFID has already laid the foundation for this, further research and development is needed to enable such a pervasive networking world, which should be flexible, adaptive, and secure. Reflecting current trends and future directions in the industry, The Internet of Things provides a comprehensive technical and practical guide to recent advances in pervasive networked systems through detailed discussions, real-world case studies, and experience reports.
