Towards a IoT Framework for the Matchmaking of Sensors’ Interfaces

[1]. With the diffusion of sensors, smart devices,, the advances in connection technologies, the Internet of Things (IoT) has become a very popular topic. Because of the creation, expansion of new, existing sensor networks, the need to define a common standard for sensors' interfaces representation has arisen. Currently it is difficult to make different sensors, sensors' networks interoperate seamlessly, since their interfaces are not always well specified or are not ready to be adapted immediately to one another. In order to overcome the current lack of a shared standard, in this paper we propose an IoT framework which, by analysing sensors' APIs descriptions in C/C++ or Java (and potentially mroe languages),, expanding such analysis with that of RESTfull interfaces exposed by smart-sensors, tries to integrate different sensors' interfaces into a common Aggregator. Such an Aggregator relies on wrappers, adapters, either automatically built or provided by experts, to make programming, using sensors from different providers completely opaque to the users, who only sees a set of general, abstract functions available. Semantic technologies are used to support the creation of such wrappers, to easily discover, categorize new sensor types.
