Study Notes
Introduction to IoT Using Case Studies
- An Internet of Things (IoT) system is an interconnected network of "things" (devices).
- Things can sense surrounding data, process it, act based on the processed data, and communicate with other things.
- Communication between things is done using various methods like Wi-Fi, LoRaWAN, and Cellular.
IoT Network Architectures
- Peer-to-Peer Network: Devices communicate directly with each other.
- Star Network: Devices are connected to a central hub.
-
Hierarchical Network (Cloud-Fog-Edge): Combines processing and storage levels.
- Cloud: Centralized analytics and storage.
- Fog: Local processing close to devices.
- Edge: Real-time processing directly on devices.
Case Studies
-
Ride-Hailing Services (Uber/Ola): Connect drivers and passengers efficiently.
- Sensors: GPS, accelerometer.
- Communication: Cellular (4G/5G.)
- Processing (e.g.): Pricing, route optimization, driver-passenger matching, basic navigation.
- Considerations: Minimal delay, data privacy, scalability.
-
Smart Road Traffic Monitoring (Including Air Pollution): Monitors traffic and air quality.
- Sensors: Traffic cameras, air quality sensors (e.g., PM2.5, NOx).
- Communication: LoRaWAN, cellular/Wi-Fi.
- Processing (e.g.): Object detection/filtering, traffic analysis, pollution mapping.
- Considerations: Bandwidth, data integration, power efficiency.
-
Smart Water Meters: Automatically monitor water usage.
- Sensors: Flow sensors.
- Communication: Narrowband IoT (NB-IoT), LoRaWAN.
- Processing (e.g.): Anomaly detection, billing, trend analysis.
- Considerations: Power efficiency, data volume, real-time alerts.
-
Sports Vests: Monitor athlete health and performance.
- Sensors: Heart rate monitors, GPS, accelerometers.
- Communication: Bluetooth/Wi-Fi.
- Processing (e.g.): Real-time tracking, performance analysis.
- Considerations: Real-time feedback, wearability, data fusion.
Comparative Analysis of Case Studies
- The analysis compares aspects like sensors, communication networks, edge/cloud processing, and considerations for each study case.
IoT Design Considerations
-
Components: Sensors/actuators, edge/cloud processing, communication networks, security/privacy.
- Sensors/Actuators: Collect data, power, durability, accuracy.
- Edge/Cloud Processing: Real-time tasks, bandwidth reduction, large-scale analytics.
- Communication: Data transfer, bandwidth, power constraints, range.
- Security/Privacy: Encryption, regulations, data protection.
-
Parameters: Processing capability, communication requirements, real-time/non-real-time processing, power efficiency, storage considerations.
Key Takeaways
- IoT applications are diverse, spanning various industries (transportation, health, etc).
- Choosing between edge or cloud processing depends on various factors.
- Effective IoT systems balance considerations like efficiency, scalability, and privacy.
Discussion Questions
- Trade-offs between edge vs. cloud processing in IoT.
- How to ensure scalability and security in large-scale IoT applications.
- Example of another IoT application with its components and considerations.
