hey cybrid,
Thanks .I m sorry to say you that I am looking for the source code of 802.16, not the NS-2.
I have one more question also , Is this protocol(802.16) is already developed by any simulator.
Thank you verry much.

Source code of 802.16? 802.16 is a protocol, which means it's up to you or some software vendor to implement it in some programming language first.

You're probably looking for the protocol definitions. Maybe this site will help you:

Hey,
I m confused now.I want to enhance some security features to 802.16 .But I dont have any idea where can I work and where to get the source code.Doiing some calculations on paper takes one month, But its a master thesis..I want to work on it.
Thankig you.
