NCTUns Simulation Tool for WiMAX Modeling

This paper describes the NCTUns simulation tool that facilitates the WiMAX studies of network behaviors and performance analysis. We compare NCTUns with ns-2, QualNet, and OPNET Modeler. The design paradigms of these tools are elaborated. Then we enumerate the WiMAX-related functions that can be simulated by these tools. The performance of NCTUns is studied by an Ethernet network simulation and a WiMAX network simulation.
