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.
