Abstract

We present a simulation testbed for wireless and mobile telecommunication systems, a two-stage PCS parallel simulation testbed which makes use of a conservative scheme at stage 1, and of time warp at stage 2. While time warp is considered to be an effective synchronization mechanism in parallel and distributed discrete event simulation (PDES) it is also well known for its instability due to rollbacks and its devastating effect, i.e., series of cascading rollbacks, among other factors. Thus, our primary goal is to study the impact and the importance of partitioning in our PCS model while reducing significantly the number of rollbacks
