Re: [ns] implementation of snoop agent at base station

2012-11-16 Thread nicholas mbonimpa

Hullo mate,

When the error on the link is small, you will not notice a difference.

Snoop just like any other link layer solution was designed to enhance TCP
performance in wireless or random error environments.

In a lossless environment, the setup with or without snoop will yield very
similar, if not the same results.

So, to notice a difference you need to keep varying the packet loss rate on
the link where snoop is in charge. Then you do the same for an end to end
connection (i.e. without snoop) and compare the results.

The example MySnoop.tcl has an uniformly distributed random variable
error model that you can integrate into the example Snoopns2.tcl that
worked for you.

You'll notice that as the variable set loss_prob 10  grows, there'll be a
difference in performance when snoop is used, and when snoop is absent.

That should get you there.

Kind regards,

Nicholas Mbonimpa

 But, just for the beginning, you can use xgraph to visualise the outputs
 then have a rough idea on the throughput / bandwidth behaviour.

 I guess you can now move on from here, and try out a couple of other
 interesting scenarios.

 I'm glad I've been of help.

Re: [ns] Getting error when running a tcl script after adding a new routing protocol

2012-11-06 Thread nicholas mbonimpa

Hullo Shalom,

You've most probably not gone through all the necessary steps of adding a
new protocol.

Most importantly, you need to modify the Makefile.in file in the ns-2.34

then run make again to create the right executables for your protocol.

I have also attached a pdf (it was sent by someone on this email thread a

It's a simple 3 node configuration example demonstrating how Snoop works.

Snoop is configured on the middle node, which interfaces between the other
two nodes.

The sending node runs Reno, and the third node acts as the sink.

Re: [ns] Segmentation fault

2011-08-10 Thread nicholas mbonimpa

Hi Zeinab,

Segmentation faults are usually due errors in the Code you've implemented in
the C++ domain. They are mainly caused by wrong pointers, when you try to
access some memory location which has been freed. That's just one scenario.
There you have to debug the C++ code it on your own, step by step.

Sometimes they are also due to wrongly implemented connections (taking into
perspective the agents attached to the nodes) in your tcl code. For example,
if you attach an forwarding agent to a sink and expect it, without any
modifications, to send packets downstream, you'll most probably get a
segmentation fault.

Re: [ns] warning: Please use -channel as shown in tcl/ex/wireless-mitf.tcl syntax error in expression $i $val(nn) : extra tokens at end of expression while executing

2011-08-09 Thread nicholas mbonimpa

Hi Manish,

Do not worry about the warning message. If your setup is ok, the simulation
will run well.

From a look at the code lines you've pasted here, the error message is most
probably due to a missing operator in the line below.

{$i  $val(nn) }

This is because both i and val(nn) are variables and there should be an
operator relating them if the for loop is to make sense.


for {set i 0} {$i  $val(nn) } {incr i}

That aside, you are most probably running a wireless or wired-cum-wireless
simulation. Depending on how your ns is installed, your simulation may not
run, if you are using the random scene generating files. If that happens,
copy your script to the directory ~/tcl/ex/ and run it there. It will
work.

I hope this will help.

[ns] Fwd: error running wireless1 from Marc Greis tut

2010-10-22 Thread nicholas mbonimpa

Hi,

copy the file in the directory *~/tcl/ex/ *and run it there.
*
*
It is shown in the warning.
*warning: Please use -channel as shown in tcl/ex/wireless-mitf.tcl*
*
*
It should work after that.

It's because the example is using the random scene generating files which
are defined in the tcl directory.

Kind regards
