IoT platform for Smart Cities: requirements and implementation case studies

Internet-of-Things (IoT) is considered as the key player to move forward the Smart City vision. Indeed, pervasive devices can enable a fain-grained monitoring of buildings and energy distribution networks. Thus, such information can be used to enhance energy optimization in our cities. However, interoperability among heterogeneous devices is a challenging task. Furthermore, all these IoT devices produce a huge amount of data that must be collected and post-processed, thus entering into the Big Data domain. Therefore, a distributed IoT platform for energy management has to be designed for i) enabling the interoperability among heterogeneous IoT devices and ii) handling such huge amount of data. In this paper, we describe the requirements to be addressed in order to develop an IoT platform for Smart City. We also present two distributed IoT platforms we developed to improve the energy management in Smart City. Finally, based on our experience in a real-world case study, we provide an estimation of the amount of energy-related information our presented platforms have to manage.
