DIMA: Distributed IoT Modeling Architecture

In this work we present the Distributed IoT Modeling Architecture (DIMA) which is a novel, scalable, distributed framework for designing and deploying IoT systems based on a defined mission objective. DIMA assumes a centralized control source. However, while that controller is needed to interpret how the system should act given some set of environmental measurements, it is not involved in the moment-to-moment decisions of the network. Instead, the central controller defines the functions by which the system acts but lets the individual system elements deal with measuring the environment and reacting to events in real time. To do this, DIMA represents the IoT network as a set of actors and sensors. The sensor measurements are fed directly to the actors to make local decisions. The actors make decisions based on this local information and on objectives set by the central controller. This architecture allows DIMA to approach optimality without the delays and bottlenecks caused by centralized processing of all of the sensor information. We present an output of DIMA using intrusion detection and infrastructure modeling representations of IoT systems.
