NS2 extension with Directional Antenna

[tibm]

I have a small problem in my simulation, I appreciate if you could help me in debugging this. I am working on topology control and power saving in ad-hoc networks using directional antennas. Recently we found a patch for NS2.30 along with a Directional-antenna C++ Module. I installed this version and made the necessary changes made by the author. His web page was removed recently and I found the same in google catche,

**broken link removed**

On patching ns2.30 with MW-node it generated a demo example mw-node-ex.tcl in tcl/ex. I executed it and there were no errors, but after I added the C++ module and tried to execute the same code its showing me the following error.

WirelessPhy: antenna lookup of Antenna/OmniAntenna failed

Rest of the demo examples in ns2 are being executed normally. I even tried including his few lines of code that he was taking at the end in the above link. But it to turns out with the same error. Please help me if you know any thing about such sort of errors or any info on how to add a module to ns. I know you are very pre occupied and I am really stuck and I appreciate if you could help.
