1. Integrated Environment For Studying Network Effects on SCADA Systems Andrew Davis, Gabor Karsai, Himanshu Neema, Annarita Giani, Bruno Sinopoli, Rohan Chabukswar • Demonstration • An inexpensive and affordable approach for small-scale experimentation and education • Allows desktop and portable realization • Simulink model for chemical process plant (Tennessee Eastman) • Simulink model for robust controller • OMNeT++ model for network and DDOS network attack • Necessity & Goal • Challenges For Model & Simulation Integration • Heterogeneous modeling for various domains, heterogeneous simulators and emulators for different domains • A complex scenario may simulate Human Organization/Co-ordination in Colored Petri Nets (CPN), Controller/Plant Dynamics in Simulink/Matlab, Computing Systems in DEVS, 3D Environment in Delta3D and Network Architecture and Behavior in OMNeT++. • CPN (Human organizations) • Simulink (Dynamic systems) • DEVS (Discrete-event systems) • Delta3D (Physics, graphics) • OMNeT++ (Network) • How can we integrate the models? • How can we integrate the simulated heterogeneous system components? • How can we integrate the simulation engines? • Goal • An overarching integration model that connects and relates the heterogeneous domain models in a logically coherent framework. • An underlying software infrastructure that connects and relates the heterogeneous simulators in a logically and temporally coherent framework. • An environment to integrate and execute heterogeneous domain specific simulation models or ‘real’ system components. • Leverage C2WT Technology • DoD/HLA was chosen as the basis for a run-time integration platform. • Designed as a simulation integration platform, the High Level Architecture (HLA) is a general purpose architecture for distributed computer simulation systems. • It has sophisticated support for coordination among simulation engines, managed by a Run-Time Infrastructure (RTI). • Open-source and commercial implementations are available • C2WindTunnel Adds — • Model based integration of domain specific simulations • Data models • Integration models • Deployment models • Transformations(import, export of models, code generation) • Scenario design • Monitoring and logging, data analysis Matlab/Simulink Simulation: Controller Model Sensor data stream Actuator data stream Omnet++ Simulation: Network model Sensor data stream Actuator data stream Simulation: Plant Model ?
