A Gateway/Middleware HLA implementation and the extra services that can be provided to the Simulation

ABSTRACT: This paper describes a Gateway/Middleware High Level Architecture (HLA) implementation and the extra Services that this implementation provides to a Simulation. This paper relates what Services (Data Distribution Management (DDM), Time Management, Agent, Dead Reckoning, Time Stamping, Update Filtering, Coordinate Conversion, MOM) a Gateway/Middleware HLA implementation could provide, and which are over and above what is available from the Run Time Infrastructure (RTI). This paper characterizes knowledge areas that we re−investigated in order to prepare to incorporate Gateway/Middleware Services into our HLA interface called the Simulation Object Middleware Classes (SMOC) Gateway. A sample Service called "SMOC Agent Class " will be discussed which handles Simulation situations like, "Federates who abruptly leave the federation without correctly resigning and the corresponding state of the undefined federate.&quot
