RESUMO

Distributed and parallel simulations can be used to create virtual collaborative environments that involve human beings in applications of training, entertainment, etc. The High Level Architecture - HLA, developed by the Defense Modeling and Simulation Office (DMSO) of the North American Department of Defense - DoD and adopted by IEEE for modeling and simulation of high level, is a framework of simulation standardization that basically aims at the reuse and interoperability of/among simulations. The HLA comprises the following services: Federation Management, Declaration Management, Object Management, Ownership Management, Time Management and Distribution of Data Management (DDM). RTI (Run-Time Infrastructure) is the implementation of the interface specification of HLA, whose main objective is to separate the communication from the simulation. A version of the RTI (RTI kit version 1.3 from Georgia Institute of Technology - Georgia Tech) was installed in the cluster of the Computer Department of the Federal University of São Carlos. This version consists of a set of support libraries for real-time distributed simulation. The problem with this version of the RTI is that it has many limitations, such as lack of support for human interaction. In order to overcome these limitations, an architecture was developed and evaluated, as part of this work, that uses the JXTA platform to initiate federates (simulations) and federations (set of federates) at runtime web services. This architecture aims to manage the distribution of data among federates, one of the most important services for distributed simulations.
