Study Notes

Internet of Things (IoT) Definition

The IoT is a network of interconnected physical objects, equipped with sensors, software, and technologies that allow data exchange with other devices and systems over the internet.
These objects are also known as “Things”, “connected devices” and “smart devices”.

Basic Building Blocks of IoT

Sensors: The front-end of IoT devices that collect data from their surroundings (sensors) or provide data to their surroundings (actuators).
Processors: The brain of the IoT system, responsible for processing and extracting valuable data from raw sensor data in real-time. They can be controlled by applications and perform encryption and decryption.
Gateways: Responsible for routing processed data to specific locations for utilization. They provide network connectivity, essential for communication in any IoT system.
Applications: Software programs designed to interact with users, gather, process and analyze data, and control IoT devices. They provide functionalities such as data visualization, alert systems, and remote control.

Characteristics of IoT

Dynamic & Self-Adapting: IoT devices can adjust their operations based on changing conditions, user context, or sensed environment, e.g., surveillance cameras adapting to day or night, or adjusting resolution based on motion detection.
Self-Configuring: Enabling a large number of devices to self-configure, setup networking, and fetch software upgrades with minimal user intervention.
Interoperable Communication Protocols: Support various interoperable communication protocols to interact with other devices and the infrastructure.
Unique Identity: Each device has a unique identifier (e.g., IP address) allowing for individual identification and operation.
Intelligent Interface: Adapt based on context, allowing communication with users and environmental contexts, enabling queries, monitoring, and remote control.
Integrated into Information Network: Devices are integrated into the information network, allowing communication and data exchange. They can be dynamically discovered by other devices or applications, and describe themselves for interaction.

How IoT Works

A vast network of interconnected devices collects and transfers huge amounts of data.
This data is transmitted to large cloud servers globally.

Advantages of IoT

Easy Access: Real-time information is available from anywhere with an internet connection and a smart device.
Quick Operation: Automation and data flow enable faster task completion, e.g., automating routine tasks.
Data Monitoring: Offers access to previously challenging data, e.g., monitoring product expiration dates for safety.
Following New Standards: Continually evolving technology, allowing for updates and advancements.
Better Time Management: Efficiently manages time by allowing users to perform tasks remotely, e.g., checking news during commutes.
Automation and Control: Provides automated control of physical devices through interconnected networks.
Cost Saving: Reduces costs by enabling efficient communication between devices, saving energy and reducing manual labor.

Challenges of IoT

Privacy: Protecting individuals' personal information collected and transmitted by IoT devices.
Security: Vulnerability to cyberattacks and data leaks. Organizations must implement robust security measures like encryption, firewalls, and regular updates.
Scalability: Managing the increasing workload and number of users without performance loss.
Data Management: Effectively managing and storing large amounts of data generated by IoT devices.
Network Capacity: Ensuring sufficient network capacity to handle the increased volume of data and communication.
Device Management: Efficiently managing the growing number of IoT devices, including configuration and maintenance.
Reliability: Ensuring consistent functioning of devices over time, despite potential hardware or software failures.
Device Failure: Designing reliable devices that function correctly, even in harsh environments.
Network Connectivity: Maintaining stable and reliable connections between devices and the network.
Data Accuracy: Ensuring accuracy and reliability of collected and transmitted data.
Power Consumption: Balancing battery life with device functionality. Finding solutions for frequent recharge and battery replacement.
Lack of Skill Set: Requiring qualified personnel to handle complex development challenges and ensure successful implementation.
Deployment Challenges: Structured and well-planned deployment approaches are crucial for successful implementation of IoT solutions. This involves careful hardware and software selection, network infrastructure planning, and development of a robust security strategy.

Disadvantages of IoT

Dependency on Technology: Reliance on internet connectivity for functionality, rendering it useless without a connection.
Loss of Data: Potential for data breaches exposing personal information.
Operation Complexity: Involves complex, behind-the-scenes operations that can be difficult to debug when errors occur.
Inter Compatibility: Challenges arise when devices from different manufacturers are connected, due to potential compatibility issues.
Less Employment of Low-Educated Workers: Automation of daily tasks may lead to job losses for non-educated workers.
