Abstract: The high level architecture(HLA) is a framework facilitating the development of distributed simulations. Recently, much research and development has centered on addressing the shortcomings of the HLA. Using Web services to extend HLA simulation system can solve current problems and improve the interoperability of the system. The paper describes the benefits of using Web services. The methods for using Web services to extend HLA simulation system are given.
