When it comes to the Internet of Things, protocols and standards are sometimes disregarded (IoT). Also most of the time, the industry’s focus is on communication. While communication between devices, IoT sensors, gateways, servers, and user apps is critical to the IoT, it would be impossible without the correct IoT protocols.
1.MQTT:
A lightweight IoT data protocol is MQTT (Message Queuing Telemetry Transport). It has a publisher-subscriber messaging mechanism and also enables easy data transfer between devices. The architecture of MQTT is also its key selling point. While its genetic makeup is simple and light, allowing it to create gadgets with low power consumption. It’s also based on the TCP/IP protocol.
2.CoAP:
A CoAP (Constrained Application Protocol) is a protocol for the application layer. The Hypertext Transfer Protocol (HTTP) is the foundation of the World Wide Web’s data transfer. While the existing internet framework is freely accessible and usable by any IoT device, it is typically excessively heavy and power hungry for most IoT devices.
3.HTTP:
The HTTP (Hyper Text Transfer Protocol)has high cost, battery life, high power consumption, and weight concerns. Nonetheless, it is still in use in several businesses. Manufacturing and 3-D printing, for example, rely on the HTTP protocol because of the vast volumes of data it can transmit.
4.WebSocket:
WebSocket was first developed as part of the HTML5 project in 2011. WebSocket’s common connectivity protocol, like CoAp’s, helps to ease many of the complexities and challenges associated with managing internet connections and bi-directional communication.
5.XMPP:
This communication IoT protocol for message-oriented middleware was developed in 1999 by the Jabber open source community and was originally intended for real-time communications. It is based on the XML language. It allows two or more network clients to exchange structured yet extendable data in real time.
