Study Notes

The Internet of Things (IoT) Ecosystem

The IoT connects devices to the internet, revolutionizing how we live and work.
Examples of IoT devices include TVs, air conditioners, lightings, industrial pumps, heart rate monitors, glucose monitors, and vehicles.
In 1982, a coke vending machine at Carnegie Mellon University was connected to the internet, marking an early example of a device communicating over the network.
This machine reported its contents remotely, allowing technicians to monitor its stock levels.
ARM estimates that by 2035, there will be one trillion connected devices.

Components of the IoT Ecosystem

There are three main components in an IoT ecosystem:
- Devices (Things, Objects, Machines, Nodes, Sensors): Collect data through sensors and can process information.
- Gateways: Manage communication between devices and the cloud, using different protocols.
- Platforms: Provide the infrastructure for applications to use and manage IoT data.

Data Collection and Processing in Devices

Data collection: Devices use sensors to gather information about their environment.
- Temperature sensors measure temperature.
- Motion sensors detect movement and presence.
- IP cameras capture images and video feeds.
Data processing: Devices can process collected data to make it more meaningful and reduce network load.
- Aggregation: Reduces data volume (e.g., by finding averages) to avoid overwhelming the network.
- Sorting: Organizes data for easier analysis.
- Validation: Ensures data accuracy by identifying and correcting errors.

Gateways: Bridging the Gap

Gateways connect devices using various protocols (e.g., Bluetooth, Zigbee, LoRa) to the cloud using a common protocol (e.g., HTTPS).
Gateways can perform edge computing:
- Bringing computing capabilities closer to data sources.
- Minimizes latency and cost, improves reliability, and enhances security.
- Offers real-time services, intelligent data processing, and data aggregation.

IoT Platforms: Enabling Applications

IoT platforms are sets of components that allow developers to:
- Create applications that remotely collect data from IoT devices.
- Manage device connectivity.
- Ensure secure communication.
- Develop applications for diverse use cases.
There were over 620 publicly known IoT platforms in 2019, showcasing the growing importance of this area.

Applications of IoT Across Sectors

Manufacturing: Proactive maintenance, asset performance management, detecting impending equipment failure.
Automotive: Monitoring vehicle performance, alerting drivers of potential issues.
Transportation and Logistics: Rerouting vehicles based on real-time data, track-and-trace inventory, temperature monitoring for perishable goods.

Big Data: The Result of IoT

IoT generates massive amounts of data.
Big data requires specialized techniques and technologies to extract meaningful insights from large and complex datasets.
The size of big data is constantly growing, with datasets measured in terabytes, exabytes, and zettabytes.
