Research on Distributed Simulation of HLA Based on Grid

The Grid provides a service platform of coordinated resource sharing and application development and execution. However, developer had to establish communication mechanism by using grid service to develop distributed simulation. The HLA-based simulation is short of dynamic discovery and resource utilization. This paper propose an implementation for HLA distributed simulation on the grid to overcome the defects of both technologies. A framework is proposed which describes the design of Grid services components and scheduling of calling sequence. It resolves the problems of dynamic distribution of resource , dynamic monitoring of situation and dynamic migration of tasks, and an experiment was provided at the end of the paper.
