The productivity and revenue of a company depend clearly on the correct corporate decision making and the management of productive data. Since most industries want speed and impact in their systems, the implementation of an IoT network manages to connect both field-mounted devices and sensors, as well as automated devices such as robots, which provides a considerable advantage within the planning. In this paper, two conventional IoT communication protocols are compared, such as the AMQP and CoAP, both within an automated system, making use of low-cost devices such as RaspBerry cards. The results obtained show that the CoAP protocol is designed to be so small that it fits inside a microcontroller, however, it does not provide satisfactory communication speed, but it can be fully applied in cyber-physical environments, in another aspect the AMQP protocol is more complex, there is no official support and you need bigger installation packages; but it provides a higher communication speed. In the present paper, analyze these behaviors and other questions with respect to both IoT protocols, how and why they should be implemented in an automated system. |
