Hierarchical Simulation Architecture of Data Distribution Management System in Distributed Networks Environment

In large-scale interactive simulation based on HLA, it has become an instant problem to construct distributed networks simulation with flexibility and high efficiency. HLA provides the possibility for large-scale interactive simulation through data distribution management (DDM). Procedure and theory of data distribution were discussed and a hierarchical simulation architecture of DDM system was structured with characteristic of distributed networks. Furthermore, a new simulation strategy was proposed for hierarchical DDM system. Performance of this system was discussed and feasibility and advantage of hierarchical simulation architecture are available.
