Sistema web para la gestión de dispositivos lot y móviles

Abstract

In this work, a web system was developed for the management of IoT and mobile devices, considering that these devices are essential for communication, work, educational and entertainment activities. In the Information Technology program, a new laboratory with numerous mobile devices was implemented. However, there is no usage control or history that allows tracking the actions performed. Therefore, it was proposed to implement a web system for the control of tablets in the IoT laboratory. This system allows to designate a time for the tablets for academic use. For its development, the IoT Methodology was applied, focused on three main phases: Brainstorm, Build and Tune, each one facilitating the proper development of the prototype. The application of MQTT allows continuous communication with the devices, providing the ability to block them, see their location and effectively manage their use. For the development of the web system, an ESP32 was used as a server to host the web page, in addition to the PlatformIO framework and programming languages such as HTML, JavaScript and C++. A mobile application was also created in Android Studio to send the location to the web system, manage the connection to the broker and the geofence radius. The prototype was tested with 45 mobile devices in the laboratory, evaluating the quality of the software in terms of performance efficiency, temporal behavior, resource utilization and capacity. It was found that the web system had an efficient response time, provided that the internet bandwidth was good and stable. Resource utilization was managed appropriately thanks to the temperature evaluation on the server, and the capacity of the web system was efficient, allowing the number of connected devices to be effectively displayed. A good internet connection is recommended to use the system.
