Uma arquitetura orientada a serviços para integração de redes de sensores e atuadores heterogêneos na internet das coisas.

Abstract

The vision of Internet of Things enabled the development of a diverse range of applications and service not possible before due to a number of limitations. Despite some remaining problems still exists on hardware, such as limited processing power and battery usage, researches indicates that in 2016, more than 6.4 billion devices will be connected. The high diversity of the sedevices creates the need of a infrastructure capable of managing high ly heterogeneous devices and their hardware limitations. This work proposes an service-oriented architecture to integrate Io Tdevices and solvemostissues that this integration brings. Using this architecture, services and applications will be able to access sensors and actuators from the web using data models from repositories on the Internet. The management of connected devices is performed by a middleware that can be connected directly to the devices or through gateways that can translate information to the communication technology used (ie. Bluetooth, ZigBee, and others). This proposal was evaluated with the development of a middleware based on the UPnP specification and an Android application to simulate sensor data. Results from this evaluation shows the feasibility of the solution with the integration with applications, services and other architectures available on the Internet through the web using the same data model.
