There are several protocols and standards commonly used in ๐๐จ๐ systems to ensure interoperability, secure communication, and efficient data exchange as defined in the Infographic. Here are some of the key ones:
-
๐๐๐๐ (๐๐๐ฌ๐ฌ๐๐ ๐ ๐๐ฎ๐๐ฎ๐ข๐ง๐ ๐๐๐ฅ๐๐ฆ๐๐ญ๐ซ๐ฒ ๐๐ซ๐๐ง๐ฌ๐ฉ๐จ๐ซ๐ญ):
MQTT is a lightweight messaging protocol designed for efficient communication between IoT devices and the server or cloud. It follows a publish-subscribe model, allowing devices to publish data to topics and other devices or applications to subscribe to those topics to receive the data. -
๐๐๐๐ (๐๐ฒ๐ฉ๐๐ซ๐ญ๐๐ฑ๐ญ ๐๐ซ๐๐ง๐ฌ๐๐๐ซ ๐๐ซ๐จ๐ญ๐จ๐๐จ๐ฅ):
HTTP is a widely used protocol for communication between web browsers and servers. In the context of IoT, HTTP is often used for device management, configuration, and data retrieval. -
๐๐จ๐๐ (๐๐จ๐ง๐ฌ๐ญ๐ซ๐๐ข๐ง๐๐ ๐๐ฉ๐ฉ๐ฅ๐ข๐๐๐ญ๐ข๐จ๐ง ๐๐ซ๐จ๐ญ๐จ๐๐จ๐ฅ):
CoAP is a lightweight application-layer protocol designed for constrained devices and networks, such as those found in IoT deployments. -
๐๐๐๐ (๐๐๐ฏ๐๐ง๐๐๐ ๐๐๐ฌ๐ฌ๐๐ ๐ ๐๐ฎ๐๐ฎ๐ข๐ง๐ ๐๐ซ๐จ๐ญ๐จ๐๐จ๐ฅ):
AMQP is a messaging protocol that enables reliable and secure communication between devices and applications. It supports asynchronous, message-oriented communication patterns and provides features such as message queuing, routing, and transaction management. -
๐๐ข๐ ๐๐๐:
Zigbee is a low-power wireless communication protocol specifically designed for IoT devices. -
๐-๐๐๐ฏ๐:
Z-Wave is a wireless communication protocol primarily used for home automation and smart home applications. It operates in the sub-GHz frequency band and offers low power consumption, long-range coverage, and mesh networking capabilities. -
๐๐จ๐๐๐๐๐:
LoRaWAN (Long Range Wide Area Network) is a low-power, wide-area networking protocol designed for long-range communication with low-power IoT devices. It enables devices to communicate wirelessly over long distances while conserving battery life. -
๐๐๐ ๐๐ (๐๐๐ ๐๐ง๐ข๐๐ข๐๐ ๐๐ซ๐๐ก๐ข๐ญ๐๐๐ญ๐ฎ๐ซ๐):
OPC UA is a widely adopted industrial communication protocol for machine-to-machine communication in industrial IoT systems. It provides a secure and scalable framework for interoperability between devices, machines, and industrial software systems.
These protocols and standards play a crucial role in enabling seamless communication, interoperability, and security within IoT systems. The specific protocols used in an IoT deployment depend on factors such as the application domain, device capabilities, network infrastructure, and specific requirements of the system.
