IoT message communication protocols are a set of standard protocols that are used to facilitate communication between connected devices in an IoT system. 


    These protocols are used to transmit data, control devices, and manage the overall connectivity of the system. Some examples of IoT message communication protocols include:
  • MQTT: The MQ Telemetry Transport (MQTT) protocol is a lightweight messaging protocol that is designed for low-power and low-bandwidth devices. It is often used in IoT systems to transmit data between devices and servers in a publish/subscribe model.
  • CoAP: The Constrained Application Protocol (CoAP) is a messaging protocol designed for use with constrained nodes and networks in IoT systems. It is similar to HTTP in functionality but is designed to be more efficient in terms of bandwidth and power consumption.
  • AMQP: The Advanced Message Queuing Protocol (AMQP) is an open standard for message queuing that supports flexible messaging for enterprise systems. It is used for high-throughput, low-latency communication between applications and devices.
  • XMPP: The Extensible Messaging and Presence Protocol (XMPP) is an open standard for real-time communication, which uses a publish-subscribe model. It is used for instant messaging and presence notifications.
  • STOMP: The Streaming Text Oriented Messaging Protocol (STOMP) is a simple text-based protocol that allows clients to connect to a message broker, such as a message queue, and to send messages to or receive messages from the broker.
  • DDS: Data Distribution Service (DDS) is a middleware protocol that enables real-time, scalable, and high-throughput data communication for distributed systems.
  • JMS: Java Message Service (JMS) is a messaging protocol that enables communication between two or more components in a distributed system, it's implemented in Java.
  • Kafka: Kafka is a distributed streaming platform that is used for building real-time data pipelines and streaming applications. It is designed for high-throughput, low-latency, and fault-tolerant communication.
        These protocols are widely used in IoT systems to facilitate communication between connected devices. They offer different trade-offs in terms of bandwidth, power consumption, security, and other factors, and choosing the right protocol for a given application will depend on the specific requirements of the system.
