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.
