Hi,

I got TG installed today and it works fine under XP.
I have read the TG MANUAL and Pedro's pages very carefully. But plz
permit me to ask a few questions concerning the use of TG for analysis
of trace(.tr) outputs got after simulating 3 adhoc routing protocols
under similar mobility and traffic pattern in ns2. only AGT and RTR
traces were ON in my tcl script. MAC trace was OFF. Traffic type: cbr

I'm interested in these metrics : delay, jitter, loss rate.
For eg. I have 3 (.tr files): 1 for dsdv, 1 for dsr and 1 for aodv in
new wireless trace format:


1) do I need the (.tr.ip file)for TG in a 100% adhoc scenario?
2) I guess DC(direct connection)and IDx1 should be OFF?
n/b: all nodes are mobile and multihop communication occurs over
a 500 * 500 area.
3) I'm confussed about the actual settings needed to get jitter
results for each .tr file using TG.
4) I'll really appreciate if one could tell me a simple way to use TG
to analyse each of these 3 .tr files with a view of finding delay,
jitter and loss rate in each file.

for eg:
1) load each trace : (file -> open or trgraph aodr.tr)
2)..... etc.

4) Also a way to plot the graphs showing delay, jitter, loss rate
against time, or other possibly variables.


Thanks in advance.

N/b:

Delay: time to transmit a packet from the source(AGT) to the
destination. (possibly average delays for all flows per .tr file)
Jitter:
Loss rate: packets sent by source but not received at destination;

Hello
May i ask you how dou load ur trace file for trace graph and you get the out pur result??
I need a very simple out put ..
first of all i would like to know how we can calculate the CPU usage of MANET and then how to show it using Trace graph?
may you plz let me know what is the advantage of trace graph com[pare with ACCESS??
I am new memeber..no idea
TQ in advance
regards

1) typically, the 100% adhoc scnenarios does not use hierarchical addresses. Only in this case you don't need the .tr.ip file

4) find exactly the exact name of the graphs and options that you need in tracegraph, then create a TG script to generate the results automatically, then create a bash script to process them sequentially, then generate the graph using my gnuplot front-end, eg:


for fich in "aodv dsr dsdv"; do
tracegraph $fich.tr -script my_script.tg
done
plot.sh *.results
