Re: [ns] Metric troubles
Perhaps I have found an answer for some of my questions below, but most of them are still standing. Here is a snippet I found in an example trace file at: http://www.cs.odu.edu/~mweigle/research/netsim/intro/tracevar.out And here is a snip of what that says: # time srcnode srcport dstnode dstport variable value 0.0 0 0 -1 -1 cwnd_ 1.000 0.00610 0 0 2 0 cwnd_ 2.000 0.01219 0 0 2 0 cwnd_ 3.000 0.01222 0 0 2 0 cwnd_ 4.000 0.01829 0 0 2 0 cwnd_ 5.000 0.01832 0 0 2 0 cwnd_ 6.000 0.01835 0 0 2 0 cwnd_ 7.000 The headers there is one thing I was looking for. They make some sense, but can anyone verify that they are accurate? And that doesn't address the apparent scale issue I saw with the 'time' value.

But what is RTT and how is it calculated? Is it simply for that one packet? Does it actually calculate the return ACK to the sender as part of the RTT (which is what we would like, I suppose)? And why the drastic difference in the time fields? What units is the 'cwnd_' time field in? It doesn't seem to match up too closely with the packets from the full trace file.
[ns] How to introduce an error model between two mobile nodes
I tried something like this, but it gives me an error. set em [new ErrorModel] $em set enable_ 1 $em unit pkt $em set bandwidth_ 5M $em ranvar [new RandomVariable/Uniform] $em drop-target [new Agent/Null] $ns link-lossmodel $em $node_(0) $node_(1) Where node_(0) and node_(1) are mobile nodes.

[ns] Other Trace variables - T_RTT
Hello all, yet again. :)
I mentioned in my earlier post about one of my output files only having
one line in it (for rtt_). Well, I have tried again with another
variable and it also has only one line in it. What's going on? Here's
the one line:
0.0 -1 -1 -1 -1 t_rtt_ 0
Here's the TCL:
for {set j 1} {$j=$NumbSrc} {incr j} {
set tcp_src($j) [new Agent/TCP/Reno]
$tcp_src($j) set window_ 256
$tcp_src($j) set fid_ $j
#Trying a new variable to trace: T_RTT_
set t_rtt_trace [open t_rtt.tr w];
$tcp_src($j) attach $t_rtt_trace;
$tcp_src($j) tracevar t_rtt_;# trace t_rtt
# tracing TCP congestion window variables
set cwnd_trace [open cwnd_.trace w];
$tcp_src($j) attach $cwnd_trace;
$tcp_src($j) tracevar cwnd_; # trace cwnd (which also
tracks RTT?)
}
The trace on CWND_ comes out just fine, I think. (Yeah, see previous
messages on that, too.)
Thanks,
J

[ns] help with ns2voip module
Hello, I recently found a ns2voip++ module (http://cng1.iet.unipi.it/wiki/index.php/Ns2voip%2B%2B) for ns2 and I would be needing that module for my research. I am not able to find the proper documentation of this module which describes different functions used in the voip module. If some one has used this module or familiar with this it would be great if I could get some helping hand. Thank You Vin

[ns] how to install NIST-Mob in sn-2.29 manually .
good day everyone , i hope you all having a great time .. dear all you have been very helpful i have a request , i need to install the nist-mob in my ns2 but im using ns-2.29 version so in order to complete the installation in need to configured some files manually and i really don't know how , i do have the steps on how to do it but is just not clear to me , can you please walk me through these steps .

hi friends, I am doing my project on Trust management in MANET using NS2. For that i am using DSR as routing protocol. the problem is when two nodes communicating each other they are not using intermediate node to forward the packets. how to make them to use the intermediate node. either i have to reduce the nodes communication range or is there is any other way to do that. node1 to node3 via node2 ??? -- Your's Rams
