Review of technologies and platforms for smart cities

Abstract

The importance that data have taken on in recent years, mainly due to technological evolutions (mainly in connectivity and processing capacity) and the reduction of associated costs, means that cities, generators of large volumes of data, invest and bet on infrastructures that analyze the data to obtain benefits. Such has been the importance that much of the efforts of computer scientists have focused on developing tools and platforms that allow cities to make the most of their information, becoming smart cities. This article presents a review of the definitions that the term smart city has received, as well as a review of the functionality of the most used platforms that give technological support to cities.
