Efficient parallel simulation of large-scale PCS networks

Recent technology for cellular wireless networks makes an easily modifiable , fast simulator necessary to gauge the performance of personal communicati on service (PCS) networks. Due to enormous computational requirements by a sequential simulator for complex systems, parallel discrete-event simulatio n techniques are often studied to reduce execution times. In th is paper, w e develop discrete-event modeling and simulation methodologies for wireless PCS networks. Our approach differs from the previous schemes in that it ex ploits event precomputation and the model independence within the PCS netwo rk components. Experiments are conducted to validate the developed approach , and promising results are reported.
