A Quick Guide to Understanding IoT Application Messaging Protocols
IoT and connected devices use different communication and messaging protocols at different layers. While developing an IoT device, the selection of the protocol largely depends on the type, layer and function to be performed by the device. MQTT, XMPP, DDS, AMQP, and CoAP are a few of the widely used communication protocols for the IoT application layer. Let us understand each of them in detail. In today’s time, networking with smart devices and IoT is increasing largely due to the ongoing technological revolution across the globe. People are increasingly using IoT and connected devices to automate industrial operations, control city traffic, track health, control home appliances, manage the fleet of vehicles, etc. Smart devices like phones, wearable devices, kiosks, appliances, and automobiles use the internet to connect with other devices and exchange information and data with servers to perform different operations. There are two ways these devices can connect to the internet
