DEVS-based simulation web services for net-centric T&E

Abstract

Current test and evaluation (T&E) systems are not sufficiently well integrated with defined net-centric architectures to support system-of-systems and enterprise level testing. This paper discusses a test and development environment using Discrete Event System Specification Modeling Language (DEVSML) and the Service Oriented Architecture (SOA) framework. The underlying DEVS Modeling Language is built on XML and provides model interoperability among DEVS models hosted at remote network addresses. We describe the client application that communicates with multiple servers hosting DEVS Simulation services and the underlying SOADEVS framework. We show how SOADEVS is positioned to address the need for a DoD Architecture Framework, DoDAF-based net-centric paradigm for test and evaluation at the system-of-systems and enterprise systems levels. The SOADEVS framework provides the needed feature of runtime composability of coupled systems using the SOA framework.
