Abstract

Internet of Things (IoT) is creating an environment where devices form an intelligent network, generating demand for the development of new applications. To facilitate development, IoT platforms offer features that abstract complexity from the application developer\'s point of view. Currently, there are different IoT platforms, public and private, on which applications for industry, smart cities, among other business domains are implemented. However, applications or services developed on one platform do not necessarily interact with applications and services developed on another platform. In this way, this work proposes SToIC, a model of interoperability and portability layer that acts in the application layer of different IoT platforms and provides an interface that can be used to create multiplatform applications, allowing greater reuse and resource savings, in addition to interoperability between them. To arrive at SToIC, the research started from the recognition of the state of the art in IoT platforms and their resources through a tertiary literature review, in which 49 platforms were identified and 11 categories of resources offered to the developer were detected. Then, SToIC was designed and the process was defined by which portability and interoperability in the application layer could be achieved. Soon after, through dynamics carried out with members of 8 different projects of the Technological Research Institute of the State of São Paulo (IPT), the noise analysis and mapping project, the Barulhômetro, was selected to create the SToIC proof of concept. Then, implementation of SToIC was carried out based on the Fiware and Watson IoT Platform (WIP) platforms, in addition to the resources required by the Barulhômetro application and modifications that were made to this application, so that it became multiplatform, being compatible with the implementation SToIC. SToIC reached the level of semantic interoperability and implemented the interoperability standards \"interplatform access\", \"platform independence\" and \"high level of service facade\". (AU)
