This paper introduces the basic concept of HLAbased distributed simulations. As for the 'bottomneck' problems of computing resources wastes, dynamic imbalance of the task load and the difficulty of storing and processing plenty of data, the limitation to HLA-based distributed simulation technology is mainly analyzed. What′s more, combined with the characteristics of grid technology, the advantages of grid technology in distributed simulation application and the grid service and the realization method of OGSA are also explored. With the cross grid project of HLA-based distributed simulation application under grid environment as an example, a grid-enhanced HLA/RTI infrastructure and a three-level migration approach of HLA to the grid are introduced. Finally, the development prospect of HLA-based distributed simulation technology and the possible problems that may arise are also discussed.
