Distributed Simulation Architecture with New Time Management Method

In the current distributed simulation applications,the time management in HLA is used rarely.The basic reason is pointed out that the logical time in HLA is simulation time with semantic in nature,which brings distributed simulation some disadvantages,such as low performance and hardly interoperatility.To solve these question,the causal time without semantic was introduced to ascertain the causality between messages,and the architecture(Multi-Layer Architecture,MLA named in the paper)for distributed simulation was put forward whose infrastructure is named Message Transport Infrastructure(MTI).In MLA,causal time encapsulated in MTI is transparent to federation,and simulation time in federation as a whole can be chosen at will.Based on the method dividing the causal time and simulation time,MLA enables the information encapsulation and anti-encapsulation between the different levels,and improves the federation execution process.The MLA can help to advance the concurrence between simulation applications,increase the reusability and interoperability between simulation models,and reduce the models exposure to evolving standards.
