Análisis de una red inalámbrica mallada autoconfigurable, utilizando el módulo NodeMCU ESP32 con el estándar 802.11

Abstract

Nowadays, wireless technologies are on the rise; nevertheless, the use of wireless mesh networks using the IEEE 802.11 standard with low-cost devices has not been much studied. Therefore, the present work aims to present an experimental study of meshed networks with self-configuring and autonomous nodes that allow communication between them by sending unicast and broadcast traffic for evaluation.

This work begins with a brief description of wireless mesh networks and the characteristics of the NodeMCU ESP32 device, followed by the study of development environments that best adapt to the device.

The second chapter describes the requirements that the wireless mesh network must have, as well as the development of scripts for unicast and broadcast transmissions.

The third chapter shows, the results and the analysis of the metrics evaluated in the different tests applied to the network.

The fourth chapter presents the conclusions, which have been reached after carrying out the analysis of the metrics obtained, in the same way the recommendations related to the subject are presented in this chapter.

Finally, in the annexes section you will find the installation manual for the free access libraries and environments, as well as the scripts developed for unicast and broadcast transmission.
