Semantically Enriched IoT Gateway for Wearable Devices

With the advance of wearable devices, an IoT (Internet of Things) gateway should support the efficient forwarding, processing, and provisioning of the streaming data obtained from them. We propose a semantically enriched IoT gateway working on a smartphone for wearable devices. The proposed gateway supports (a) an efficient consolidation and compression of heterogeneous streaming sensor data, (b) privacy preserving data processing by semantic reasoning, and (c) a selective data sharing through their social networks according to a degree of sensitivity. Experimental results with the prototype implementation show the potential of the proposed IoT gateway for novel user experiences based on semantic web technologies.
