A Discrete Event XML based System of Systems Simulation for Robust Threat Detection and Integration

In a System of systems (SoS) consisting of heterogeneous independently operable systems, effective communication among the systems is essential. These independent systems need to understand each other through effective communication in or order for them to establish a SoS. Thus, there is a need for a common language which wraps the data that is sent and received from a system within a SoS. This paper presents and extends the application of Extensible Markup Language (XML) to represent data communicated among systems without underlying differences in hardware/software of the individual systems. Moreover, since the operation of each system is asynchronous in nature, the entire SoS can be considered as an event driven system. This paper extends an XML based SoS simulation framework to simulate a robust threat detection and integration problem. The DEVSJAVA software is used as the discrete event simulator. Finally, XAIL based encapsulation is created in the DEVSJAVA environment to create the common language for the heterogeneous systems in a SoS.
