Looking to simulate wireless networks

I was given a fun project to try out:

• to simulate a corporate wireless network at work.

I'm trying to due it within packet tracer and GNS3. However they want me to simulate Aruba network equipment. The OS and licenses aren't a problem. Just simulating a wireless network topology (say 1 controller, and 1 access point sending traffic to and from wireless devices)... is.

If anyone has any advice or experience doing this please let me know.
