Monitoring, IoT Devices, and Semantics.

Efforts to improve Internet of Things (IoT) device interoperability for monitoring are still required. This demo paper proposes monitoring infrastructure safety and security with the use of semantics. We make use of an ontology we proposed for interoperability in the IoT, the Connectivity Management Tool Semantics (CMTS) ontology. We demonstrate its use and the advantages it provides by monitoring a bridge, a crucial infrastructure that must be verified in near real-time. Two Raspberry Pi devices with sensors are used to monitor the inclination and vibration of the bridge, sending the data to a cloud server, which handles the ontology data-model. We also provide a web visualization tool, developed to assist users of the ontology to comprehend the status of the system's entities.
