Study Notes

Introduction to IoT

IoT stands for the Internet of Things
It's a network infrastructure with self-configuring capabilities
Uses standard interoperable communication protocols
Physical and virtual "things" have identities, attributes, and personalities
Seamlessly integrated into the information network
Often communicate data associated with users and their environments

IoT Outline

IoT definition
Characteristics of IoT
Physical design of IoT
Logical design of IoT
IoT protocols
IoT levels and deployment templates

Self-Configuring

"Self-configuring" in IoT refers to the ability of devices and systems to configure themselves automatically without manual intervention
This enhances the scalability, efficiency, and adaptability of IoT systems

Interoperability

Interoperability in IoT refers to the ability of different devices, systems, and applications to work together seamlessly, enabling them to exchange data and utilize each other's functionalities
Crucial for a cohesive IoT ecosystem, allowing diverse devices from various manufacturers to communicate and operate effectively

Intelligent Interfaces in IoT

Intelligent interfaces in IoT leverage data, context, and advanced technologies to provide intuitive, efficient, and personalized experiences for users
Key features include Natural Language Processing (NLP), Context Awareness, Machine Learning (ML), Visual Analytics, Gesture and Touch Control, and Augmented Reality (AR)

Characteristics of IoT

Dynamic & Self-Adapting
Self-Configuring
Interoperable Communication Protocols
Unique Identity
Integrated into Information Network

Dynamic & Self-Adapting IoT

Dynamic and self-adapting IoT refers to systems and devices that can automatically adjust their operations and configurations in response to changing conditions
This enhances efficiency, resilience, and user experience of IoT applications
Key characteristics include Dynamic Behavior (systems changing functionality based on conditions), Self-Adaptation (devices adjusting parameters automatically), Context Awareness (systems interpreting surroundings), Learning Capabilities (incorporating machine learning algorithms), and Resilience (recovering from disruptions).

Unique Identity in IoT

Unique identity is essential for identifying and managing devices in a vast IoT network
Each IoT device must have a distinct identity for effective communication, security, and data management
Methods of assigning unique identities include Static IDs (permanent and hard-coded), Dynamic IDs (changeable based on network conditions), and Hierarchical Structures (structured organization of devices)

Integrated into Information Network

Integration into information networks is a fundamental aspect of IoT, enabling devices to communicate, share data, and collaborate effectively within larger systems
Integration enhances the functionality and utility of IoT applications across various sectors
Benefits of Integration include Enhanced Data Sharing, Improved Efficiency, Real-time Monitoring and Control, and Scalability (ability to accommodate new devices/services)

Physical Design of IoT

"Things" in IoT usually refer to IoT devices with unique identities capable of remote sensing, actuating, and monitoring capabilities
IoT devices can exchange data directly or indirectly with other connected devices and applications
Data can be processed locally or sent to centralized servers for processing

Generic Block Diagram of an IoT Device

IoT devices consist of several interfaces for connections to other devices (wired or wireless)
Interfaces include I/O for sensors, internet connectivity, memory and storage, and audio/video

IoT Protocols

List of protocols including 802.3 Ethernet, 802.11 WiFi, 802.15.4 LR-WPAN, 2G/3G/4G, IPv4, IPv6, 6LoWPAN, TCP, UDP, HTTP, COAP, WebSocket, MQTT, XMPP, DDS, AMQP
Protocols are designed for constrained devices/networks (e.g., COAP), full-duplex communication (e.g., WebSockets), or efficient communication in constrained environments (e.g., MQTT).

2G, 3G, 4G, and LTE

2G, 3G, 4G, and LTE are generations of mobile network technologies, improving communication capabilities and data speeds over time
2G focused on digital voice communication
3G offered digital voice, text messaging, and limited data services (up to 64 kbps)
4G brought significant advancements in data speeds, capacity and performance (faster download/upload speeds)
LTE, an enhancement of 4G, further improved data speeds and network performance.

Logical Design of IoT

Logical design of an IoT system is an abstract representation of entities and processes, without low-level implementation details
An IoT system comprises of functional blocks for identification, sensing, actuation, communication, and management

IoT Communication Models

Request-Response model - client sends requests to server, server responds with data
Publish-Subscribe model - publisher sends data to topics, subscribers receive data from the topics
Push-Pull model - producers push data to queues, consumers pull data from queues
Exclusive Pair model - bidirectional communication with persistent connection between client and server

IoT Communication APIs

REST-based APIs use request-response model for resource access
WebSocket-based APIs offer bi-directional communication between clients and servers

IoT Levels & Deployment Templates

Components include Device (identification, sensing, actuation), Resource (access, processing, storage), Controller Service (interaction with web services), Database (storage), Analysis Component, Application
IoT levels (Level 1-6) describe different architectures from single device with local data storage to large, distributed systems with cloud-based storage and analysis.
