MPC controller as a service in IoT architecture

These days a term Internet of Things (IoT) is often mentioned in commercial and academic sphere so it can sometimes sound as a buzzword. Nevertheless the IoT idea moving the world further in terms of almost unlimited connectivity of fog components, meaning sensors, actuators, gateways, with cloud components meaning high cpu power and memory capacity computers in data centers with all kind of software services connectable, that can add value to data coming from fog to cloud and from cloud to fog. By this approach of connecting fog with cloud it is possible to do cpu and memory power demanding operation in cloud and so sophistically affecting actuators in the field. This papers is inspired by the IoT architecture and proposes an idea of Controller as a Service approach in automation. MPC online method was chosen as demanding controller and is exposed as a service for use of everyone or better every internet thing. The complicated computation is done in the cloud, only communication with cloud is needed in fog area.
