Ns2 Extension with directional Antennas

directional antenna ns2

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

}
global errorInfo

(procedure "new" line 3)
invoked from within
"new BiConnector/NetworkInterface2/FullStack/Wireless 0 _o16 _o21"

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.

ATTACH IS THE PATCH FOR NS-2.33 FOR DIRECTIONAL ANTENNA SUPPORT

Assuming $NS2 points to the directory where you have the ns-2.33 sources, and that you’re using the ns-allinone-2.33 release, here’s what you have to do:

cd $NS2
patch -p1 < dir-antenna.patch
patch -p1 < multi-if.patch
./configure --with-otcl=../otcl-1.13 --with-tclcl=../tclcl-1.19
make
export NS_ANTENNA_FILE=$NS2/mobile/antenna.txt
