Adding Directional Antenna and Multiple Interface Support to ns-2.33

February 6, 2009

Following this post, I ported the directional antenna and multiple interface support from TeNs to ns-2.33.

You can download my patches, and re-compile ns-2.33 to enable support for directional antennas and multiple interfaces. Don’t forget to set the NS_ANTENNA_FILE environment variable.

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

hi,
I am trying to simulate wireless link with multiple interface, when i use adhocRouting protocol WLSTATIC, i get following error

Could you please tell me what could be the problem ?

hi,
thanks so much for sharing this.

do you also have a sample TCL script on how to use the directional antenna & multi-interface module? or a readme me will do as well

hope its not too much trouble

fizi, this page has sample code: http://www.cse.iitk.ac.in/users/braman/tens/

Mates,

I tried to install it on NS2.33 to experiment it. Interesting to find, in the patch, it is not using static routing as TENS thus the sample coding might not really apply directly.

Wonder how a packet be sent up and front when more than one directional antenna loaded of a particular node. How this can be controlled via flow control.

Hmm..Still half way on installation as have been attacked with numerous bugs when “make” after installing the patch.

Do share if you have your user experience here.

Hi,
Thank you for the 2.33 patch… I have incorporated this patch into my build and it seems to work.
You mentioned that the multi interface functionality currently works only with AODV routing protocol. I was wondering whether it would be possible for you to it to DumbAgent as well? That would be pretty useful.. thanks again!

regards,
Swaroop

Swaroop, I don’t remember saying anything like that. multiple interfaces should work regardless of the routing protocol.

Hi,
Everything is fine after patching.
Now I need some help regarding a TCL script. I have downloaded sample_long.tcl from http://www.cse.iitk.ac.in/users/braman/tens/
I hope to get more support from u in future.

Hi,

Thank you for the 2.33 patch!, When I installed the patches, and executed my file, I have the next error:

Could you please tell me what could be the problem ?

Hi, I am using ns2.34
Can the patches be used for ns2.34?

Thank you very much.

I changed the code to the following.
It is run, but while visualizing the nam file, “node 0 is not defined”.

I haven’t tested these patches on ns-2.34, and I’m not sure if they will work. If anyone can create updated patches for 2.34, I’d be happy to post them here.

Also, please refrain from posting lengthy code samples directly or asking questions related to ns2, but not my patches.

In the future, I won’t approve comments containing more than a few lines of code. You can use Gist or Pastebin and post a link here.

For other ns2 questions, please use Stack Overflow. I wil take a look at your question if you send me a link. You can find my email address on the About page.

Hi,

I installed the patches you posted here but i got the error when i execeute a multiinterface (I used net_if(0) and net_if(1)) wireless node simulation.

_o14 reset: can’t read “reset”: no such variable
while executing
“$netif_($i) reset”
(procedure “_o14″ line 4)
(Node/MobileNode reset line 4)
invoked from within
“_o14 reset”

The command $ns_ node-config -numif 2 is passed but i have this error. Can you help me?

Thanks

serkan, I don’t think the error you’re getting is caused by my patches. Even if it was, I couldn’t help you without seeing your code.

Hi,i try to install it in NS2.33, when I executing the sample_long.tcl,there is some
error like this:
fopen:No such file or directory
can’t open /home/dixun/ns-allinone-2.33/ns-2.33/mobile/antenna

Could you please tell me what could be the problem ? i have set the NS_ANTENNA_FILE environment variable.
thank you
dixun on April 2, 2010 at 04:01
everything is ok.thank you!
export NS_ANTENNA_FILE=$NS2/mobile/antenna.txt is right!
i forget .txt

Hi,

Can the multiple interface support code be used to simulate 802.15.4 networks?

Thank you.

Best regards,
Lup.

Hey I have the same problem that Jimmy from Ecuador had. I installed the patches and while running the sample.tcl or any other one from the samples I encounter the error:

Could you please help me

Thank you Very much
