Today, we’ll examine the difference between MQTT (Message Queuing Telemetry Transport) and HTTP (HyperText Transfer Protocol).

These two protocols are widely used in IoT and the Internet but have distinct purposes and designs. Let’s break them down in a simple way based on the diagram.

1. Abbreviation and Overview

• MQTT: Stands for Message Queuing Telemetry Transport. It is a lightweight protocol for IoT systems with limited bandwidth and power.
• HTTP: Stands for HyperText Transfer Protocol. It is commonly used for web communication, such as browsing and APIs.

2. Architecture

MQTT: Works on a publish/subscribe model. Devices (clients) can publish data to topics, and others can subscribe to receive updates.

• Example: A temperature sensor publishing updates while a user’s smartphone subscribes to receive the data.

HTTP: Operates on a request/response model. The client sends a request, and the server responds.

• Example: Browsing a website, where the browser requests a page, and the server sends it.

3. Complexity

• MQTT: Less complex, making it easier to implement in resource-constrained devices like IoT sensors.
• HTTP: More complex, as it involves more overhead to handle documents and media.

4. Transmission Protocol

• Both protocols run over TCP (Transmission Control Protocol), which ensures reliable data delivery.

5. Protocol Design

• MQTT: Data-centric, designed to handle small, lightweight data packets efficiently.
• HTTP: Document-centric, designed for transferring web pages and files.

6. Message and Header Size

MQTT:

• Message Size: Smaller, as it uses a binary format.
• Header Size: Only 2 bytes, making it very lightweight.

HTTP:

• Message Size: Larger, as it uses ASCII format, which is not as efficient.
• Header Size: 8 bytes, which adds overhead.

7. Port Number

• MQTT: Uses port 1883.
• HTTP: Typically uses port 80 or 8080 for communication.

8. Data Security

• MQTT: Supports SSL/TLS, ensuring secure data transfer.
• HTTP: It does not have built-in security, but you can use HTTPS for secure communication.

Key Differences Summary

• MQTT is lightweight, efficient, and ideal for IoT applications where devices have limited power and bandwidth.
• HTTP is more suitable for web-based applications requiring rich document exchange.

Practical Applications:

1. Use MQTT for IoT systems like home automation or sensor networks, where data needs to be transmitted efficiently in real-time.
2. Use HTTP for applications like APIs or websites requiring document exchange and richer content.

Discussion Question: Based on these differences, which protocol is better suited for an IoT application like a smart home system? Let’s discuss it!

Selangor, Malaysia – February 3, 2025 — Favoriot, a leading IoT platform provider, is proud to announce its latest Favoriot Partner Network (FPN) initiative to transform the landscape of IoT education through strategic collaborations with educational institutions. This collaboration bridges the gap between academic knowledge and industry demands by equipping students with practical IoT skills and industry-recognised certifications.

Empowering Students Through Two Key Approaches:

1. Embedding Favoriot IoT Platform into IoT Courses and Labs
   Educational institutions can directly integrate Favoriot’s IoT content into their courses, syllabi, and laboratory environments. This approach enables students to gain hands-on experience with real-world IoT platforms, fostering practical skills in device management, data analysis, and system integration. Upon completing these IoT courses, students will be awarded the Favoriot Certificate, co-endorsed by both Favoriot and the respective institution, enhancing their employability in the IoT industry.
2. Short-Term IoT Training Conducted by Certified Lecturers
   In addition to curriculum integration, Favoriot offers specialised 2-3 day IoT training programmes conducted by university lecturers. To ensure high-quality training, these lecturers must pass the Favoriot Certificate Examination to become certified trainers. This certification process guarantees that students receive instruction from knowledgeable educators who are well-versed in the latest IoT technologies. Students who complete these intensive training sessions will also receive the Favoriot Certificate, recognised by industry players.

Quality Assurance Through Certified Educators
Favoriot maintains stringent quality control measures by requiring that only lecturers who have successfully obtained the Favoriot Professional Certification are eligible to teach IoT courses or conduct training sessions. This ensures consistent, high-quality instruction across all partner institutions.

A Commitment to Industry-Ready Talent Development
“Our collaboration with educational institutions is part of Favoriot’s commitment to nurturing the next generation of IoT professionals,” said Dr. Mazlan Abbas, CEO of Favoriot. “By embedding our platform into academic environments and empowering educators through certification, we are creating a robust pipeline of talent equipped to meet the evolving demands of the IoT industry.”

About Favoriot:
Favoriot is a leading IoT platform company dedicated to simplifying the development of IoT applications through secure, scalable, and user-friendly solutions. With a strong focus on education, smart cities, and industrial IoT, Favoriot is at the forefront of driving digital transformation across various sectors.
