The Internet of Things

• Machine-centric

• Connects low-end devices

• Trillions (1012) rather than billions (109) of nodes

• Universal Identification

– EPC

• Universal Addressing

– IPv6

[Elgar Fleisch 10]

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

RFID em acção

[Roussos06]

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

Near-field RFID

• LF (Low Frequency): [30 .. 300] kHz

• HF (High Frequency): [3 ..30] MHz

• Inductive coupling

• Load modulation

Shower Analogy

Far-field RFID

• UHF(Ultra-High Frequency): [300..3 000] MHz

• MW (Microwaves): [2,5 .. 5,8 GHz]

• Wave coupling

• Backscatter
