Research of MQTT, CoAP, HTTP and XMPP IoT Communication protocols for Embedded Systems

Abstract

This paper describe most popular IoT protocols used for IoT embedded systems and research their advantage and disadvantage. Hardware stage used in this experiment is described in this article – it is used Esp32 and programming language C. It is very important to use corrected IoT protocol that is determines of purpose, hardware and software of system. There are so different IoT protocols, because they are cover vary requirements for vary cases.
