Análisis de interoperabilidad de plataformas IoT aplicado al desarrollo de un sistema de monitoreo de polución de aire para la ESPOCH.

Abstract

To be implemented in the modular School of engineering electronics a network of wireless sensors with different platforms IoT to analyze the feasibility of interoperability enabling to determine what are the problems that affect the network or the integrity of the information. The implemented network is the result of a preliminary analysis to determine the platforms that will make it according to costs, benefits, and its extensive use in the development of IoT projects, being the richest Arduino, Intel Galileo and Waspmote who, sensing performed the measurement of environmental contaminants in the Ecuador determined by national air quality Plan. Selected to control pollutants were carbon monoxide (CO), nitrogen dioxide (NO2), and particles smaller than 10 micros (PM10), selected by the availability of its sensors on the market and affordable costs. In the area to monitor the influx of vehicles was found as the main generator of pollution. The samples were taken during seven days, time in which each node was in charge of delivering 144 daily samples to the system, all data collected by the sensors nodes were centralized through a Java application to run on the charge base station receive, to process and store correctly received date in a database. The values obtained from the air pollution monitoring system are presented through a web page containing details of the system, as well as a quantitative and graphical representation of all collected values, for each of the nodes of the network during the period of time it was encountered operational. With the results concluded that the interoperability of different platforms IoT is feasible in a 99.9%, as the data received showed a very low level of losses at a 0.1% generated by the Arduino platform; overall the results demonstrate that the proposed network is fully functional and complies with the requirements of a system sensor like the one presented, however, is recommended to develop systems of platforms IoT homogeneous since it allows to reduce time of configuration and deployment, unlike a heterogeneous system where you need a custom configuration for each of its nodes and is therefore increased considerably the time needed to have fully functional network.
