Study Notes
IoT Smart Things
- Smart things consist of sensors, communication interfaces, operating systems, and actuators responsible for data collection and transmission.
- They transfer sensor data to a connected coordinator or gateway.
Coordinator
- Manages multiple smart devices and sensors, ensuring effective communication and control.
Networking Infrastructure
- Comprises various wired and wireless networks (e.g., Wi-Fi, Bluetooth, ZigBee, LoRaWAN) enabling connectivity of smart things to IP-based networks through IoT gateways.
IoT Gateway
- Can be a physical device or software facilitating connectivity between sensor devices, coordinators, and the IoT Cloud.
- Preprocesses sensor data at the edge, including compression to minimize transmission costs.
- Translates different network protocols to enhance interoperability among smart things.
IoT Cloud
- Consists of high-performance servers designed to store, process, and manage large volumes of data for analysis.
End-User Devices
- IoT applications are accessible through mobile and computing devices, prioritizing user-friendly interfaces to enhance customer experience.
IoT Applications
- Available globally, covering a broad spectrum from home automation to industrial automation.
- Encompass various security measures: physical device security, data security, network security, and cloud security to protect against specific IoT attacks.
Security Challenges
- Implementing security across diverse IoT devices is complex and requires understanding of unique constraints.
- Comprehensive security approaches must include identification of IoT components and an end-to-end perspective to align functionalities with system components.
Key Functionalities in IoT Systems
- Firmware Upgrading: Keeping smart things updated with the latest code for optimal sensing.
- Pairing: Connecting smart things with the controller device (IoT Coordinator).
- Binding: Configuring smart things for Internet access through the controller.
- Local Authentication: Verifying the controller on a dedicated port of a smart thing.
- Local Control: Commanding smart things via the controller using local wireless connection.
- Remote Authentication and Control: Needed when a controller is connected to smart things over the Internet.
- Sensing and Notifications: Smart things alert the controller with relevant data.
- Data Analytics: Performed on edge devices or fog nodes, while big data analytics occurs on the cloud.
