Some researchers of CRS4 Information Society group - a research centre based in Sardinia (Italy) - have chosen Paraimpu among several other Internet of Things platforms to carry out their work and experimentation focused on Semantics & IoT. This work is part of the research and development of various projects in the field of Smart Cities.
Thanks to the Paraimpu workspace and the new APIs, Cristian Lai and Antonio Pintus built a dynamic and scalable Semantic Sensor Network system, based on the platform and supporting the following features:
- Geographically distributed sensors, grouped in stations, are able to form ad hoc networking topologies; they not only send measurements data but also announce themselves and their presence in the network;
- Raw data sent by sensors is semantically annotated and on-the-fly enriched by Paraimpu as it flows through the system, using Semantic Web formats;
- A real-time, websocket-based web application shows an (always) updated interactive bubble view of the network: stations, their sensors and related measured data.
