Developing a web-enabled HLA federate based on poRTIco RTI

This paper presents an approach to implement distributed simulation software to test, validate and improve information exchange between enterprises. The approach assumes some of the recently released HLA Evolved standard web service requirements. The implementation is based on improving the open source poRTIco HLA RTI tool. The paper mainly focuses on the presentation of the HLA web-enabled federate proposed to fulfill the web service needs of the brand new HLA 1516-2010 standard. The idea is that a federate is being connected to an HLA federation based on previous HLA standards version (1516- 2000 or 1.3) and, in parallel, to other federates outside the LAN federation via the WAN. This approach intends to improve federate components interoperability and agility in a heterogeneous, distributed and dynamic context. To achieve that goal, time management mechanisms have been developed. The concept is validated through distributed simulation of a car selling enterprise modeling test case.
