MRE: A Flexible Approach to Multi-Resolution Modeling - Parallel and Distributed Simulation, 1997., Proceedings., 11th Workshop on

Multi-resolution representation of simulated entities is considered essential for a growing portion of distributed simulations. Heretofore, modelers have represented entites at just one level of resolution, or have represented concurrent representations in an inconsistent mannel: We address the question of the cost of maintaining multiple, concurrent representations. We present a brief overview of our concept of a Multiple Resolution Entity (MRE) and Attribute Dependency Graph (ADG) both originally described elsewhere, and then compare simulation and consistency costs of some approaches, including our own MRWADG-based approach, to multi-resolution modeling. The cost analysis presented here is the first known analysis of its type, and will provide a basis for simulation designers to determine the best, and most cost-effective approach to supporting simulation of entities at different levels of resolution concurrently.
