Improvement of Update Mechanism for Object Management in High Level Architecture

As the distributed interactive simulation technology,the High Level Architecture( HLA) with the common Runtime Infrastructure( RTI) services has been applied to all kinds of simulation and computation areas,which has more interoperability and interactivity.Especially,with the development of hierarchical RTI software technology,the efficiency,flexibility,and levels of resolution etc. can be improved. However,updating mechanism for object management in hierarchical RTI can't supply the dynamic object subscription to the simulation operation,specially updating limitation in consistence and synchronization. Therefore,the improvement of update mechanism for object management has been proposed,and the process of which has been described. The results of simulation showthat the improvement mechanism can achieve better updating rates and latency than traditional mechanism,considering the consistence need.
