WT Week 16

Internet of Things (IoT)

tldr - Bunch of buzzwords

The general idea of things that are readable, recognisable, locatable, addressable and controllable via the Internet

• Everyday objects includes not only electronic devices but also such as food and clothing

IoT Technology Trends

Miniaturisation of Devices

As IoT uses technologies to connect physical objects to the internet, the size and cost of electronic components have to be small.

• Semiconductor industry is doubling transistor density every 2 years ∴ allowing for smaller devices

Advances in RFID Technologies

RFID could provide streams of data that supplies information systems with real-time, item-specific data.

• RFID tags are flexible enough to be placed in extremely small spaces and locations

Internet Protocol version 6 (IPv6)

IPv6 can provide trillions of unique IPv6 addresses.

• Roughly 50 billion connected devices
• IPv6 can potentially be used to address all these devices
• Promotes end-to-end connectivity and control

Improvement in Communication Throughput and Latency

• Slide has too much crap so here’s the Ivan-style tldr - Improvements in technology improves communication throughput and latency

Real Time Analytics

IoT creates opportunities for real-time analytics

• Allows large volumes of data to be stored for analysis at a later time

Adoption of Cloud Technology

Cloud computing makes things much better by relying on the internet :)

Security

With the distributed nature of IoT devices in public areas, security is a big concern.

• Wireless sensor network connecting sensors and IoT devices often not well protected
  • Encryption techniques can be used to improve security
• Protection on IoT devices such as web cam is quite weak
  • e.g. Default passwords are used

IoT Wireless Communication Issues

• Huge volume of sensors with varied types and distributed sites need to be connected, managed and maintained
• Environments with lots of interference requires highly reliable communication
• Limited spectrum resources available for new IoT wireless network
• Outdoors environment
  • Requires low power consumption and simple architecture
  • Installation and maintenance more challenging
