Web-Based Distributed Simulations Visualization And Control With Hla And Web Services

Dynamic Data Driven Application Systems (DDDAS), systems with online simulations models fed with sensorial data from the environment, are increasingly; being used for emergency, management strategic planning. This paper describes an approach to establish the communication and exchange information among the many subsystems composing a DDDAS using the High Level Architecture (HLA) infrastructure's services. We present the LAViE-3D, a framework that generates Web-based simulation front-ends using 3D graphics to manage and control HLA-compliant distributed simulations. The LAViE-3D framework uses open-source software and is designed to make it easier to implement and deploy visualization applications on different platforms with customizable interface for simulations runtime control and management.
