Design of fog computing based IoT application architecture

With the advent of IoT technologies and standards, IoT services has become popular these days. To populate IoT service, collaboration of IoT services on service level is essential. From the viewpoint of application, most of interfaces of existing IoT services are proprietary, which induces vertical silo problem. In this paper, IoT application architecture to access multiple IoT services using fog computing is proposed. By adapting Fog computing concept to application level, the proposed architecture works as a service gateway to multiple IoT services for IoT applications. The proposed architecture is suitable to build an IoT application utilizing multiple IoT service.
