code for performance evalution of scheduling algo of wimax

I need to simulate and do the performance evaluation of scheduling algorithms for wimax ( http://www.computer.org/portal/web/csdl/doi/10.1109/WAINA.2008.151) as a preliminary for a project, urgently. Please send me the required code for this simulation.

I have already installed ns2.31 and patched wimax module by NIST. Your help will be highly appreciated.
