Partitioning PCS for parallel simulation

Parallel and distributed simulation techniques have been investigated in a number of studies as a way to decrease long execution times of personal communication system (PCS) simulations. However, most studies have omitted important issues in radio propagation in the simulations. Including these radio propagation issues makes it significantly more difficult to partition a PCS model efficiently. In this paper we consider parallel simulation of PCS models using time warp and focus on the partitioning issue. We compare base station based partitioning with channel based partitioning for an F/TDMA system. Analytical and experimental results on a shared memory multiprocessor indicate that for realistic parameters the partitioning per channel will significantly outperform the partitioning per base station.
