Modeling CPU utilization and network traffic in a distributed interactive simulation system using discrete event simulation.

摘要

Distributed Interactive Simulation (DIS) is a IEEE standard 1278 protocol used to achieve distributed simulation. The load on the CPU and the network are important factors to consider in distributed simulation. In this work, a Discrete Event model is constructed to simulate a DIS System. The model predicts the load on CPU based on "tick" time variance. The model also outputs the bandwidth usage of network as number of nodes and number of entities on each node varies. The model is validated by comparing measured experimental values with a DIS software, VR-Forces, built by MAK technologies. VR-Forces being a closed software, a surrogate was built to better validate the developed model. In the process, the battle of 73 Easting was simulated using VR-Forces to validate the model with a known valid scenario size.
