Abstract

We present a new synchronization method for parallel discrete event simulation for wireless networks. The method merges paradigms of timestepped and event-driven simulations to achieve reduction of messages exchanged between local processes of simulation. The method is particularly suitable for wireless network simulation, in which objects share the same physical medium and parallel simulation involves a significant overhead for interprocess communication. The article describes the method and compare it to conservative and optimistic synchronization methods, on the basis of results of simulations of selected wireless network model.
