DEVS/RMI - An Auto-Adaptive and Reconfigurable Distributed Simulation Environment for Engineering Studies

摘要

With the increased demand for distributed simulation and testing environments to support large-scale modeling and simulation applications, much research has focused on developing a software environment to support simulation across a heterogeneous computing network. This paper presents a new implementation of the Discrete Event System Specification (DEVS) formalism, called DEVS/Remote Method Invocation (RMI), a natively distributed simulation system based on standard implementation of DEVS. The objective is to distribute simulation entities across network nodes seamlessly without any of the commonly used middleware. The DEVS/RMI system also is built to support auto-adaptive and reconfiguration of simulations during run-time. Because Java RMI supports the synchronization of local objects with remote ones, no additional simulation time management needs to be added when distributing the simulators to remote nodes.
