Re: [ns] Fwd: Calling SystemC code in NS2

[許 涛]

*Hi

I am reading the ns-tutorial

II.1. Documentation for ns&nam

The last line has a link to
*http://www.isi.edu/nsnam/dist/archive/ns-users/

But it is unavailable?

Thanks & Regards.

Re: [ns] Help configuring simple AODV routing example

[許 涛]

Hi, Bello

I am learning that tutorial now.
I typed the code, and it run well.
If you insert "$ns node-config -adhocRouting AODV"
after
"for {set i 0} {$i < 12} {incr i} {
   set n($i) [$ns node]
}"

Variable declaration is not needed in Tcl.

Good luck.

[ns] directional antenna

[許 涛]

Is anyone using directional antenna?

I patch the source given in the following url to ns-2.34.
http://cbg.me/2009/02/adding-directional-antenna-and-multiple-interface-support-to-ns-233/comment-page-1/#comment-143

And I download the sample from tens
http://www.cse.iitk.ac.in/users/braman/tens/scripts/sample_long.tcl
Changed the sample code to the following.
It is runned, but while visualizing the nam file, “node 0 is not defined”.

[ns] UML to networks graphs

[許 涛]

hi,everyone

My question is not directly with ns2.
Is anyone use UML to show some graphs like Fig 4.28 in Computer Networks by
Tanenbaum?

Thank you very much.

You can try run the following command in terminal.

sudo apt-get install build-essential

sudo apt-get install tcl8.4 tcl8.4-dev tk8.4 tk8.4-dev
