Um middleware para a Internet das coisas
| Resumo: | After the traditional Internet (with program-to-human communication), and after the Internet of Services (with program-to-program communication), the Internet of Things is a novel paradigm of communication, aiming at integrating the state of everyday things into the digital world. But things are everywhere, have different colours, come in different flavours, so, building reliable applications that depend on such things imposes great challenges and demands for new approaches to integrate heterogeneous devices smoothly. This master thesis faces these challenges and proposes a middleware framework to manage the things networks and their data, all this supported by Web services. We designed and implemented a generic platform, where services represent network features, allowing for high level applications to interact with heterogeneous hardware using dynamic methods. When we use Web services, we benefit from an interoperable technology, cross platform and independent from programming languages, and the most important, available on the Web. These attributes makes easier building heterogeneous systems, like the Internet of Things. As we support many services, we propose an innovative search method based on an ontology that relates the things networks with the available services, allowing semantics searches through their characteristics. |
