[ns] ns-allinone-2.30 and 2.33 installation problems in linux

[crystal_maple]

Dear all,
   I have some problems when I installed ns2 in linux, I use redhat, and the
kernel version is 2.4.21-20.EL,
the gcc version is gcc-3.2.3
it shows:

The similar problem occurred when I installed ns-allinone-2.33.
Can anybody help me? Thanks very much.

Hi, all.

I applied mobiwan extension into ns2. Well, after the patch, I got the error
when I perform some test files located ns/tcl/test directory. The error

Anyone knows about these errors? Thanks in advance.

[ns] loss rate in tcl file or in ns-default.tcl file gives different results

[Semra YILMAZ]

Dear all,
Defining the loss rate in tcl script and ns code gives the different results 
(number of sent, received packets). That is, I am defining loss rate in 
ns-default.tcl file with the following line;

ErrorModel set rate_ 0.10

For example this gives the following results:
# of tcp packet sent from sender: 1955
# of tcp packet received at receiver: 1935
# of ack packet received at sender: 1722
 
Or I am defining the loss rate in tcl script with the following line
 

$ns_ node-config -IncomingErrProc losses_module 
-OutgoingErrProc losses_module 

 

proc losses_module {} {

set loss_module [new ErrorModel]

$loss_module set rate_ 0.10

$loss_module unit pkt

return $loss_module

}

For example this gives the following results:
# of tcp packet sent from sender: 5148
# of tcp packet received at receiver: 5116
# of ack packet received at sender: 5027
 
I am confused with these results. Could you please send your idea for this 
issue.
Regards,
Semra

[ns] FW: packet loss rate cannot be reached to the loss rate defined intcl

[Semra YILMAZ]

Hello,
I have sent the below message a few day ago. If anyone has any idea for the 
issue below, i will be very glad.
Thanks
Semra

Subject: [ns] packet loss rate cannot be reached to the loss rate defined intcl




Hello,
I have a question about error model in ns2. Even i define the loss rate as 10%, 
15% or 20% or more, I cannot see that kind of packet loss in simulations.
For example, I am measuring the number of TCP packet sent from sender, number 
of TCP packets received at receiver and number of ACK packets at the sender. 
But the difference between the number of TCP packet sent from sender and the 
number of received TCP packets at receiver are not so much as defined in the 
loss rate. I was expecting that if I sent 1000 TCP packets and if I define the 
loss rate as %10, 100 TCP packets should be lost. But I cannot see this result 
in my simulation. In my simulaiton the packet losses about 1 %.
My error model is as below:
$ns_ node-config -IncomingErrProc losses_module -OutgoingErrProc losses_module

proc losses_module {} {

set loss_module [new ErrorModel]

$loss_module set rate_ 0.10

$loss_module unit pkt

return $loss_module }

If anyone has an idea, i will deeply appreciate it.
Thanks in advance,
Semra

Re: [ns] Negative UID of the packets

[Amit Soni]

Hi Ns-Users,

Thank you Teerawat for your reply, but in my simulation, from 0-3.4
seconds "th->uid()" is positive but from 3.4 it goes negative. I think the
most probably reason is that the packet uid space exhausts, but then why
doesn't it shows some error. Any ways even if it goes exhausts is there
any way to wrap around the uid's , I mean renew all the uid's.

Thanks again,

Regards,
Amit Soni
