Offering web-of-things connectivity to building networks

Abstract

Building management systems (BMS) are nowadays present in new and renovated buildings, relying on dedicated networks. The presence of various building networks leads to problems of heterogeneity, especially for developing BMS. In this paper, we propose to leverage on the Web-of-Things (WoT) framework, using well-known standard technologies of the Web like HTTP and RESTful APIs for standardizing the access to devices seen from an application point of view. We present the implementation of two gateways using the WoT approach for exposing KNX and EnOcean device capabilities as Web services, allowing a fast integration in existing and new management systems.
