Research on Strategy to Improve Real-time Performance of HLA-based Simulation System

HLA has been accepted in the field of simulations and has become the common standard of international Distributed Interactive Simulation for its superiority in reusability and interoperability, but HLA/RTI has shortages in real- time simulation. The time-delay performance of several RTIs and the common methods to improve the real-time performance of HLA-based simulation system are studied firstly. Then a new approach is brought forward from the view of the simulation application system developer based on the analysis of principal influencing factors of the real-time performance of HLA-RTI, which sets a management node to manage the synchronization of each node in the simulation system. The approach is proved to be a simple and efficient method to solve the problem of the shortage in HLA-based real-time simulation system in a certain extent by experiments and usage.
