Looking for Tcl code for generating a wireless network with nam file

[geetha]

haiiii,
i am doing project in wireless networks using Network Simulator.i could not install ns-2.29.2 for the past 2 months.just now i have got it.but my project review is coming soon.before that i need to simulate a wireless enviroment.
pleazzzzzzzz anyone give me the Tcl code for generating a wireless network with nam file.

thanks in advance!!!!!!!!!!!!!!!!!!!!!
