Comparación de protocolos de comunicación para internet de las cosas (IoT)

Abstract

The purpose of this article is to contrast the communication protocols for the Internet of Things (IoT), for this, the Systematic Mapping Study is applied through which searches are made in platforms such as IEEE Xplore and Scopus, as well as with the AHP Method (Hierarchical Analytical Process) in this way the most relevant characteristics such as security are extracted, quality of service, energy efficiency, broadband and latency of communication protocols (HTTP, MQTT, DDS, XMPP, AMQP and CoAP). Subsequently, these criteria are used for the AHP Method obtaining as a result that the CoAP protocol offers 26% security, 24% latency, 21% of energy effectiveness greater than the other protocols and 22% and 19% of bandwidth and quality of service respectively, followed by the MQTT protocol with 24% security, 14% latency, 14% of energy effectiveness, 12% of bandwidth and 24% of quality of service greater than the other protocols without neglecting AMQP with 16% security, 17% of latency, 19% of energy effectiveness, 12% of bandwidth and 15% of quality of service, this protocol despite having acceptable percentages for IoT requires more physical resources with which to work, such is the case with HTTP and MQTT.
