Crowdsourcing strategies for smart cities applications

Crowdsourcing is a problem-solving model through the contribution of a large number of people and has a low cost among its main advantages. On the other hand, smart cities today comprise a multidisciplinary challenge, where they have the objective of sustainable development and improving the quality of life of its inhabitants. Thus, we see in crowdsourcing a resource capable of contributing to building smart cities. This paper investigates the existing intersection between the fields of smart cities and crowdsourcing and discover the gaps and challenges that characterize this applications context. As a result, we propose some strategies to facilitate the development of crowdsourcing applications. These strategies are then applied to the construction of several applications of this type, two of which are discussed at the end of the article.
