Sistema de control de tráfico vehicular aplicando la arquitectura Fog Computing

Abstract

ABSTRACT The fog computing communications architecture allows the implementation of applications that require real time data processing, such as traffic management through intelligent traffic lights, for this reason this project focuses on the design of a traffic control system vehicle for Cevallos Avenue and Eugenio Espejo Street in the city of Ambato, which allows to process the data in real time of the traffic volume and act automatically in the traffic light time intervals. The system design is based on the installation of a fog node or server in the fog for communication, storage and data processing through Wifi wireless communication technologies, 4G LTE cellular mobile phone networks, Mqtt and WebSocket communication protocols for IoT devices and a programming algorithm which allows to count vehicles using geofences or virtual perimeters to determine the appropriate traffic light phase, viewed through a real time monitoring web interface. The system also uses a mobile application designed to send the vehicle's GPS location, a server in the AWS cloud to obtain the historical records of the system and the construction of an intelligent traffic light prototype which allows to verify the operation of the traffic light phases. Finally, the technical parameters that fog has with respect to cloud computing are compared, obtaining advantages in fog computing since it has low latency and greater processing capacity.
