Understanding the Internet of Things (IoT)

• The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, and objects that can transfer data over a network without human interaction.
• IoT involves sensor-enabled devices communicating with each other through intermediary collection points.
• The IoT captures, transmits, manages, and analyzes data to monitor events, identify relationships, predict outcomes, and improve performance.
• IoT is a network where Cyber-Physical Systems (CPSs) cooperate using unique addressing schemas.

IoT History

• During World War II, radar technology was used to detect approaching enemy planes but lacked the ability to identify them.
• In the 1970s, the US government developed RFID to track nuclear materials, using electromagnetic fields to identify and track tags on objects.
• Charles Walton patented a card with an embedded transponder in 1973 that could communicate with a reader to unlock a door.
• In the early 2000s, Auto-ID Labs promoted the concept of connecting the world through the Internet, coining the term "Internet of Things".

IoT Drivers

• Reduced costs of CPU memory and storage enable big data collection and analytics.
• Proliferation of sensors is essential for realizing IoT opportunities.
• Lower megabyte costs increase investment in large processing systems.
• Cloud and big data provide repositories for storing and analyzing data.
• Convergence of IT and operational technology is creating a new revolution, with the Internet and industrial worlds merging.
