Local time evolution in Personal Communication Service model

Abstract

We investigate the local time evolution in the Personal Communication Service (PCS) model simulated with the parallel discrete event simulation method’s optimistic algorithm. We propose a model for the optimistic local virtual time evolution (OLVT) in PCS, which is reminiscent of statistical physics’s surface growth. We use Rensselaer’s optimistic simulation system with the Time Warp implementation. We compare the results of the simulations of both PCS and OLVT models and found good agreement. We discuss the highlights of our approach in the analysis of scalability and synchronization using the OLVT model.
