DSL methods for CPS simulation in the cloud: Experience report

Abstract

This paper presents our approach to Cyber-physical System (CPS) simulation including a number of embedded nodes that form a wireless network. On one hand, we use the NS-2 discrete-event simulator as a C++ kernel for running network simulation scenarios, while on the other hand, a combination of components written using standard Scheme as well as a number of Domain-Specific Language (DSL) instances embedded into Scheme (implementing pattern-matching, logic-relational models, and Web programming) are used in a cloud-based tool-set that supports research exploration cycle where variation in network parameters is compared to the resulting CPS performance. These components cooperate to provide an intuitive Web-based user interface, analysis tools and a seamless work-flow including visualization.
