Análisis comparativo de los protocolos LwM2M Y MQTT-SN para administración de sistemas IoT.

Abstract

The present work is focused on the analysis and comparison of the IoT management protocols LwM2M (Lightweight Machine to Machine) [1] and MQTT-SN (Message Queuing Telemetry Transport Protocol) [2], each in its scenario. This work includes three chapters: Chapter 1 covers the concepts needed to understand the operation of IoT management protocols and the tools used in the present work. Chapter 2 involves developing test scenarios, including server surveys, client encoding, and sensor readings. Each client periodically sends this information to its server (LwM2M) or broker (MQTT-SN). The study of the structure and functioning of the protocols was conducted to understand their behavior and the headers they insert. In both scenarios, the traffic flow is divided into information and administration for analysis. A test protocol was established to allow for the behavior analysis of each protocol within its respective scenario. Finally, Chapter 3 presents the volume of traffic exchanged for each protocol using graphs and tables. Testing is conducted across several environments: with information transmission, without information transmission, during video streaming, and while downloading a file. The findings and recommendations highlight the behavior of protocols within their respective scenarios in each environment and identify suitable applications for their use. Finally, the conclusions and recommendations are presented based on the obtained results.
