Building a NS-2 WPAN model

Hi , my name is jack, i’m a student in Multimedia University, Malaysia majoring in Data communications.

my question is regarding NS-2, i’m not quite used to it and i have a final year project to complete using the simulator.

i need advice on how to proceed in building a simple WPAN model to evaluate WLAN and bluetooth throughput by atleast implementing 2 MAC protocols.

i’m not sure how many nodes to implement in a simple WPAN enviroment, which requires WLAN and bluetooth present.

Guides to build the model is greatly appreciated.
