Proposal of a Web of Things Integration Pattern on the Edge-Cloud Environment

In this paper, we propose a new architecture to connect various devices in the building to the edge-cloud environment along with Web of Things (WoT) standard proposed by W3C. To cope with the current situation where most IoT devices are connected to their proprietary cloud services and their integration is performed only in the inter-cloud environment, we introduce an intermediary that can span from cloud to the edge and set up a virtual thing so that the integration can be made according to the WOT model. We evaluate POC implementation with small overhead.
