Research On Simulation Framework Of Military Electronic Information System Based On SOA

HLA is the most popular architecture used in simulation for military electronic information system. But there are many unsolved problems in HLA standard which results in the deficiency for requirements of military simulation. The kernel of Service-Oriented Architecture (SOA) is service and share. It based on open standards and protocols, has the loose-coupled characteristic which is useful for interoperability of system and the reuse of components. And no mistake, SOA is an excellent method for constructing complex military simulation system. So HLA will be replaced by the technology of SOA-based network modeling and simulation.In view of the deficiencies of HLA and the application potential of SOA in military simulation, a SOA-based military simulation system framework (SOA-MEISSF) was proposed in this theis. The framework solves the interoperability among simulation components in the WAN, improves the reuse of simulation components and recombines simulation system based on simulation services quickly.The idea applied in military simulation (HLA, SOA and MDA) and some implement technology (CORBA, DCOM and Web Service) for service-oriented architecture is analysed in the theis. With the deeply thinking of SOA and considering the requirement and characteristic of military simulation system, we propose SOA-MEISSF. And each level in the framework is explained after. Then the theis discusses the levels and design of simulation services system. Later we explain the implement and encapsulation principle for simulation services. The implement for SOA needs serials of opening technologys. We think Modeling Driven Architecture is an effective method which is appropriate for developing SOA-based simulation system. And Web Service is most viable technical approach for SOA's implement. With the thinking, the process model of developing SOA-based simulation system using MDA method and Web Service technology is presented in the theis.At last, the design and implement for a simulation applying system about dealing with radar information based on SOA-MEISSF is given.
