The Internet of Things [Elgar Fleisch 10]• Machine-centric• Connects low-end devices• Trillions (1012) rather than billions (109) of nodes• Universal Identification – EPC• Universal Addressing – IPv6
IoT applications• Health monitoring systems• Distributed awareness to natural disasters• Improve transportation – Reduce carbon footprint• Improve recycling – Using product lifetime information
RFID• Automatically identify tagged physical objects• Collect attributes such as location and time.• Information systems can keep up-to-date – Greatly improve business processes – Data is dispersed
Tag categories• Passive or battery-less – Use only power provided by the RFID reader’s signal – Smaller, more flexible – $ 0.20• Semi-passive or battery-assisted – Use a battery to boost response signal – $5• Active or battery-powered – Have additional processing capabilities and autonomy because they have more power e.g. sensors – Longer range – $ 30
