Dynamic grid-based vs. region-based data distribution management strategies in multi-resolution large-scale distributed systems

Summary form only given. Managing multiresolution simulations is a real challenge in large-scale distributed simulation systems. Various levels of resolution in a simulation, may result in inconsistencies, due to improper correlations between attributes of entities interacting at varied levels of resolution. Aggregation/disaggregation (A/D) is a method for implementing multiresolution simulations within a high level architecture (HLA) federation. This is a follow-up of our earlier work, where we studied the dynamic grid-based vs. region-based data distribution management (DDM) strategies, in a monoresolution distributed simulation system. Here, we wish to extend that work, and present a multiresolution scheme, based upon the aggregation and disaggregation (A/D) paradigm. The purpose of A/D is to ensure consistency in state updates between federates simulating objects at various levels of resolution. We present an extensive simulation experiments using several real-world benchmarks to evaluate the performance of both data distribution management schemes using our multiresolution paradigm.
