✦ Synopsis

To execute complex large-scale simulation and to share geographically dispersed data assets and computing resources collaboratively, a large-scale distributed simulation is needed. To perform such distributed simulation with reasonable communication and computation resources, several message traffic reduction schemes have been proposed. In this paper, the space-based quantization scheme is introduced as a superior solution to reduce message traffic and network data transmission load. The space-based quantization is created by combining existing quantization-based filtering concepts with a spatial encounter monitoring scheme. We study the performance of spacebased quantization schemes in centralized and distributed configurations operating on a test pursuer/evader federation withing the DEVS/HLA (discrete event simulation specification/high level architecture) distributed simulation environment. Empirical data illustrate the advantages of a distributed quantum-distribution scheme in reducing both message traffic and overall simulation execution time.
