IoT web 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 web communication protocols include:
  • HTTP/HTTPS: The Hypertext Transfer Protocol (HTTP) and its secure version (HTTPS) are widely used in IoT systems to transmit data between devices and servers. HTTP is a simple and efficient protocol that is supported by most web browsers and servers.
  • 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 web transfer 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.
  • LWM2M: The Lightweight Machine-to-Machine (LWM2M) protocol is a device management protocol that is designed for use in IoT systems. It is used to manage and monitor connected devices, as well as to perform software updates and other management tasks.
  • WebSockets: WebSockets is a communication protocol that enables real-time, bidirectional communication between a web browser and a server. It is often used in IoT systems to transmit real-time data between devices and servers.
  • AMQP: 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: 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: 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.
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.
