[ns] Busy tone in NS2 or DBTMA code

2007-02-27 Thread Mohammad Nassiri 

Hi all

I want to implement a MAC protocol based on 802.11. In this MAC
mechanism, each emitter emits   a busy tone during transmission.
Would you please tell me how I can implement busy tone in NS2. All
comments and any source code appreciated. Also I looked for DBTMA
code in NS2 but I could not find it.

Thanks in advance,

[ns] Disable ARP

2007-02-27 Thread Ahmad Khayyat 

What is the easiest way to disable the use of the ARP protocol?
I guess the IP address corresponds to the MAC address in ns-2, doesn't
it? So how do I make the LL/ARP modules use it immediately without
using ARP?

I tried adding the following two lines at the top of
ARPTable::arpresolve(nsaddr_t dst, Packet *p, LL *ll)

mac_-hdr_dst((char*) HDR_MAC(p), dst);
return 0;

but that caused strange behaviour on rare occasions, where a packet
suddenly would appear in another far node. Playing with ARP doesn't
explain the problem for me, but somehow removing those two lines
gets rid of the strange behaviour. So, what is a proper way of
disabling ARP?

Thanks..
Ahmad

[ns] Routing problem in OBS extension

2007-02-27 Thread Nipatjakorn Kannasoot 

Hi all,

I have a routing problem in OBS extension of Ns-2. Usually, when we don't
specify routing protocol to be used in the ns-2, the ns-2 will automatically
run static routing using shortest path algorithm and create routing table
for the simulation. In the OBS extension of ns-2, It defines its own
classifier (CoreClassifier) instead of using the normol classifier of the
node. Then It is replaced the normal classifier by the CoreClassifier by
using this tcl script

set cl [new Classifier/BaseClassifier/CoreClassifier]
$n set classifier_ $cl
[$n set classifier_] set address_ $nodeid

and I have to call the procedurebuild-routing-table created by the coder
of this extension in order to create normal routing table for static
shortest path

The problem is I want to run Link-state protocol instead of Static routing.
Then instead of calling the procedure build-routing-table, I use normal
ns-2 script to activate Link-state protocol, which is

$ns rtproto LS

But when I run it, it generate error message like this
*Scheduler:attempt to schedule the event with null handler.Don't do that*
I guess this is because the simulation have empty routing table -- routing
routing table is created yet

Hi,

search the mailinglist, there were recently some similar problems posted with 
solutions. One time it had to do with different bash versions, some of which 
did not like a apostrophes at a certain place, or it was some incompatible 
compiler version

Betreff: [ns] urgent : problem in installing ns2

 
  hi
  i have older version of ns2 now i uninstall that and now when i try to
  reload ns2.30 or and then other earlier version too i am getting problem in
  installing i am following these steps to install these ns2 version.  it 
  gives
  me problem in tk file installation
 
 
  i am using fedora core 4 version for linux
  i logon as root
  userid root
  password   yourpassword
 
  Place ns-allinone-2.30.tar.gz file in the directory
  /usr/src
 
  Open a terminal window and move to the /usr/src directory
  cd  /usr/src
 
  Unpack this file using the command
  tar -xvzf ns-allinone-2.30.tar.gz
 
  This will unpack the files and create a new subdirectory
  /usr/src/ns-allinone-2.30
 
  Move into the new directory
  cd ns-allinone-2.30
 
  To compile the source files enter (dot slash install)
  The dot means use the current directory
  ./install
 
 
  and this finally gives me following error
