The document discusses the Internet of Things (IoT). It describes the key elements of an IoT architecture as including connected devices that generate data, an aggregator device that acts as an internet gateway, a cloud service that logically aggregates devices for users, communication protocols, an access system for users, and security. It also lists several application areas for IoT, such as agriculture, automotive, construction, health, and more. Example use cases are automated tractors, self-driving cars, smart buildings, wearables, and predictive maintenance.

These are the sources of data and the “remote-controllable” devices. • An aggregator device or service for these peripherals which would act as an internet gateway for these devices • A cloud service which would be responsible for logically aggregating the peripherals for the end-user, like the Azure IOT service, or services running off Amazon AWS. • A comprehensive protocol system that enables end-to-end communication between the cloud, the router and the peripherals. Examples are RESTful API/HTTP, MQTT, AMQP, CoAP, etc. • An access system for end-users to retrieve information from, or control, peripherals • A comprehensive security architecture for data privacy

Application Areas • Some example industries, with associated use cases, include: • Agriculture – automated tractors, surveillance drones • Automotive – V2V communications (accident avoidance), self-driving cars, infotainment, performance • Construction – smart buildings • Fashion – color-changing fabrics • Health – air & water purity, wearable for exercise, tracking metabolic processes (insulin) • Industrial (process and discrete manufacturing) – predictive maintenance, robotics for hazard remediation / environmental monitoring • Military – drone swarms, surveillance, force protection • Realty and property management – single family home sales, big data market assessments, low-income housing • Retail sales – proximity detection and advertising • Rocketry – video feeds, weather

SUMMARY • The Term terms creation by Kevin Ashton in 1999. “Things having identities and virtual personalities operating in smart spaces using intelligent interfaces to connect and communicate within social, environmental, and user contexts” A different definition, that puts the focus on the seamless integration, could be formulated as: “Interconnected objects having an active role in what might be called the Future Internet”
