how i modify the original DSDV

[RaHeM]

hi

i want to modify the original DSDV in routing section, can i override model such as dsdv-routing-protocol.h ? 

why DSDV-example not used DSDV library such as   dsdv-routing-protocol.h ?

tnx

Yes, NS-3 is an open source project, so you can do any modification you like.

What do you mean the example does not use the DSDV library? Which example? It may use other header files that include this one (e.g. dsdv-module.h).

 

tnx

hi

tnx dear friend 

i wanna ask you more about ns3 - im new in ns3 

i wanna trace tr file for packet delivery ratio , overhead and so on , what can i do ? is there a special tool for that ? i used tracemetric but it dose not work correctly. 

i wanna create a modification of DSDV , should i create a module for that ? how can i do this ? 

Answers to these questions will help me a lot 

yours respectfully

What did not work correctly? What was the problem? If you think that your trace file is correct and the tracemetric tool is wrong, try to create your own parser with simple scripting (e.g. awk)

Have you tried FlowMonitor class in NS-3? (http://telecom.inescporto.pt/~gjc/flowmon-presentation.pdf)

It is totally up to you. If you want later to compare the original DSDV with your implementation, then I would recommend to create a new module. Read the documentation on how to do that (http://www.nsnam.org/docs/manual/html/support.html). Generally creating your own module is better because you understand and you know what you have written where as if you take the code of someone else you do not know everything.

thanks for your help

size of my tr file about 11 GB . its so big file and tracemetrics can not open this file and creates bugs.

how can i write awk script ? what is the best way to trace tr file ? is any tutorial about awk? do i exact whole information (such as packet delivery ratio , end to end delay , overhead , drops) with flowmonitor from tr file ?

11GB trace file?? How many nodes do you have? How many seconds is your scenario running?

 

One question at a time....

how can i write awk script ?

Tutorial on AWK scripting: http://www.grymoire.com/Unix/Awk.html 

If you search online you have find hundreds of other tutorial. This was just the first that came up

 

what is the best way to trace tr file ?

Since you have such a big trace file, the best way is with some scripting (awk, python, shell etc) These tools are fast and do not consume much memory.

 

is any tutorial about awk?

See the first question

 

do i exact whole information (such as packet delivery ratio , end to end delay , overhead , drops) with flowmonitor from tr file ?

Have you read the link I forwarded you? If you use FlowMonitor you do not need to create trace files.

i just run original DSDV in fallowing parameters :

node               100

wifi sink node   30

speed              20

250s simulation time

8kbps cbr traffic rate default

11 mbps phy - link layer 

2 mbps cbr threshold

2 puse time

1000*1000 room size

512 packet size

15 time interval

6 setting time

50 data start (time at which nodes start to transmit data)

my tr file about 11 gb ! it is correct ? what is the cbr threshold ? is it bandwidth ?

tnx again for you help

i studied flow monitor but i think awk scripts is better than it. but i have a problem with my tr file

format of this file is different from ns2 I dont know how i write awk code for that , its so complex but ns2's tr file is easy to trace 

thanks very much for your help
