Introduction
We use OPNET to simulate wireless data networks.
We investigate the impact of self-similar traffic on performance of a cellular digital packet data (CDPD) network.
OPNET Modeler was used to model and simulate the CDPD network of a local commercial service provider (Telus Mobility).
In our simulations we used genuine traffic traces collected from the Telus Mobility CDPD network.
Our simulation results indicate that genuine traffic traces produce:
- longer queues
- require larger buffers in the deployed network's switching elements.
