FAQ
Which protocol is the most suitable for resource-constrained IoT devices?

As its name suggests, constrained application protocol, or CoAP, is the best for resource-constrained devices. It’s lightweight, which is perfect for such environments.

Which protocols provide security in IoT?

Data protocols in IoT like MQTT, SSL/TLS, and CoAP provide secure communication.

How to choose the right protocol for your IoT project?

Evaluate your project’s power, security, and compatibility requirements. Review which protocols are necessary for every system layer, whether application, transfer, or network layer protocols in IoT. With that in mind, select the most suitable options.

Which protocol is used by IoT devices the most?

MQTT is the ultimate leader among all IoT protocols. It works well in various scenarios, making it a perfect option for different projects.

What are the two mesh protocols that are used most often with IoT devices?

The two most commonly used mesh protocols with IoT devices are Zigbee and Z-Wave. Both protocols enable energy-efficient mesh networks, providing reliable and wireless communication, especially in smart home and building automation systems.
