Improving Federation Executions With Migrating HLA/RTI Central Runtime Components

Free registration required

Executive Summary

Simulation tools are popular in the design and study of communication systems and networks. The implementation of analytic distributed simulations commonly requires a central entity to support certain tasks (e.g., time management). The HLA/RTI uses a Central Runtime Component (CRC) to this end. Because of network variability, the location of the CRC with respect to the federates may severely influence the federation execution performance. The paper proposes the optimal migration of a federation CRC to achieve better execution times. To achieve this goal, it applies an iterative search mechanism and proposes suitable cost functions to determine the optimal host.
