A DDS-based distributed simulation approach for engineering-level models

AddSIM is a component-based simulation environment that has been developed for weapon system modeling and engagement simulation. While AddSIM addresses component-based model development and reuse issues, it does not fully consider distributed simulation for massive and frequently changing data. We studied some approaches to develop an engagement simulation environment based on data distribution service for distributed systems (DDS). This article introduces three different approaches to apply DDS to AddSIM and describes their advantages and disadvantages. Then, we choose the best way to develop the mixture of AddSIM and DDS. According to the proposed approach, we explain the data exchange mechanism between AddSIM nodes and time synchronization for correct execution. We also define several DDS topic types for interoperation. Finally, we describe an anti-ship warfare case study to show the difference between AddSIM and the proposed approach.
