Abstract

This paper introduces a technique to control theoverhead of time management processes in order tomake such mechanisms appropriate for real-timedistributed simulation. A novel message accountingscheme, the offset-epoch method, is presented as a wayto increase the efficiency of time managementalgorithms by eliminating transient messages. Asynchronized lower-bound on timestamp (LBTS)computation exploits this efficiency to reduce timemanagement overheads. This approach represents onestep in bridging the gap that now exists betweenanalytic and real-time distributed simulations.
