Operating models of application protocols

Abstract

These last years the internet of things (IoT) is a buzzword in tech circles. It covers a very wide range of technologies, from embedded real-time to storage in the cloud. It s about dialogue and automating the behavior of everyday objects to provide services or send information about their state or environment to extract value. One way to interact with these connected objects is to use the application protocols. In this paper, we will present the operating models of the application protocols which are specifically designed for equipment with limited memory capacity, in computing power and in energy with a small distance. These protocols are: CoAP, MQTT, XMPP and AMQP. For these models, we used the activity diagram which is a behavioral diagram of UML, it allows to graphically represent the behavior of a method or the flow of a use case. We will adopt these models later the test of the operation of these protocols and the realization of the models of good practice of these protocols.
