Deployment of multiple software-defined and virtualized IoT gateways for smart campus

Abstract

The Internet of Things (IoT) is based on objects ("things"), which are able to communicate and transfer data. The fact generates an increase in the flow of data traffic over the network. In order to support this increase, the heterogeneity of devices and the geographic distribution have the need for an infrastructure which can handle this demand. The Institute of Informatics of the Federal University of Goias has proposed a software-defined IoT gateway thats supports for various wireless communication technologies and fog/cloud environment integration. A prototype was deployed for the queue at the University Restaurant using a single gateway IoT, which was afterwards evaluaed with good performance. In this article, the results of the evaluation of the prototype are presented, as well as the expansion of the system in a pilot project at Campus Samambaia (UFG), with the implementation of multiple gateways IoT, aiming to collect data on the amount of organic waste , monitoring of garbage levels in selective bins, temperature, humidity, gas level and video monitoring. The experiments carried out were intended to analyze the working and the capacity of the system to manage the data flow, from the sensors to the user's application.
