HLA Based High-Performance Visualized Simulation with MATLAB Seamlessly Embedded

In order to build multi-domain collaborative simulation systems, the method of making MATLAB programs join into HLA/RTI based distributed interaction simulation system needs to be studied. Aiming at giving full play to the advent-ages of MATLAB in visualization and engineering computing, improving the efficiency of collaborative simulation systems, this paper has proposed a method making MATLAB programs and SIMULINK modules seamlessly join into HLA/RTI based simulation system. The principles of the method are elaborated, and the designs of the related modules are introduced. The demonstrations and testing results show that the method could fully execute the visualized simula-tion functions of MATLAB, and has advantage in simulation efficiency over existing methods.

PaaS RTI-Supporting Distributed Simulation Interaction in Cloud Computing Age

In Cloud Computing age, distributed interaction simulation would encounter many difficulties, especially the WAN-based interaction. A scheme of remodeling the traditional RTI software to be with "Platform as a Service (PaaS)" architecture was proposed. This paper puts forward two different software architectures to adapt to different network environments. Kernel idea is encapsulating the APIs of traditional RTI to be Web Services, deploying and scheduling these Web Services on servers, so, a distributed interaction platform is provided to simulation users on WAN. Users could utilize the services from the platform to execute simulation interaction. Finally, an experiment was carried out to test the time-latency performance of the remodeled software.
