how to calculate performance metrics for wireless network using ns3 simulator

[msilini hayet]

 Dear ns-3-users

I'm new to ns-3. I'm a student and have to work on Ns-3 as a project. What I needed help for, is that if neone can guide me to calculate performance metrics such as jitter, delay, and packet loss and visualise them using ns3 simulator
I really need for your help to accomplish my work
any sugestions?
thank you in advance

you can use wireshark to analyse the pcap file, in order to get the
metrics you want.

I know that i can visualise metrics with wireshark but my problem is
haw to write a script that calculate delay, jitter and packet loss for
wireless network
or is there any script which accomplish that work
thank you

You might want to take a look at tracing subsystem.

Then, you should add timestamps as tags to all your packets and then
trace the delay (Now() - Packet's sendtime) to some file (see the
previous few threads about using tracing). Calculating jitter is just
applying some statistics to observed delays and loss of course you can
do with an incrementing packet counter tag and seeing what's dropping.

I'm not sure if such functionality is already builtin to Netdevices
for automatically adding such tags..

Hi,
This discussion is related with "Throughput at IP layer!" that I have
just replied.

You can copy great ideas from the examples folder.
wifi-adhoc.cc for example and more complete examples/stats/*

Any other ideas? sample scripts?

There is a delay and jitter estimation in the contribution directory.
I haven't even try it, I just "discover" it.
