However, the most common types of IoT application protocols include, MQTT, XMPP, DDS, AMQP, and CoAP. is an ongoing dilemma for the IoT industry; consequently, it is important to understand the pros and cons of the widely accepted and emerging messaging protocols for IoT systems to determine their best-fit scenarios.

MQTT is a communication protocol widely used in both IoT and IIoT deployments. To practice all areas of IOT, here is complete set of 1000+ Multiple Choice Questions and Answers. Hey, When you mean "resource constrained", I hope it means the availability of Wi-Fi (or internet connectivity) for the node (end device / microcontroller). It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium. It is a lightweight broadcasting system where the user can transfer and receive a message like a client. Recently, at Exadel, we encountered an interesting challenge for IoT developers.
Both protocols have their own pros and cons; Taneja explained six points of comparison for the two:
XMPP facilitates identity management, authentication, authorization, Off-the-Record Messaging (OTR), and encryption — including end-to-end encryption.
For device communication, two specialized, competing protocols stand out: Message Queue Telemetry Transport (MQTT) and Constrained Application Protocol (CoAP). MQTT, XMPP, DDS, AMQP, and CoAP are a few of the widely used communication protocols for the IoT application layer. MQTT used to stand for MQ Telemetry Transport, but is today referred to simply as MQTT and is no longer an acronym. Recently I had a discussion about using either XMPP or MQTT within an IoT project. Of course message size is only 1 aspect when choosing a … It also uses restful architecture, which is just like the HTTP protocol.
Other IoT protocols. MQTT and CoAP are both useful as IoT protocols, but have fundamental differences. There are other protocols that can be used for IoT applications like AMQP, XMPP, DDS or LwM2M.In fact, what is really important is the knowledge of one’s own business needs and requirements, awareness of the advantages and drawbacks of the protocols offered by the market, and the ability to pick the one that best suits a given use case. The main purpose of MQTT is to manage IoT devices remotely.
MQTT vs XMPP: What are the differences?
« Prev - IOT Questions and Answers – MQTT Protocol » Next - IOT Questions and Answers – XMPP Protocol XMPP is an excellent protocol for use within Internet of Things.The aim of this page, is to give a brief introduction to how XMPP can help build solid, secure and interoperable devices, services and applications for the Internet of Things.It is meant as a simple portal for people interested in IoT, providing links to more detailed information on each subject. It is designed to enable simple, constrained devices to join IoT through constrained networks having low bandwidth availability. Wondering whether to use HTTP or MQTT for your IoT application?
XMPP provides a solid, flexible foundation for security features. Every language.
