I want to simulate VOIP over P2P in Integrated WiFi/WiMAX network in OPNET Modeler. What is the procedure of setting P2P application in an application profile and what things I have to consider?
I use NS2, because WiMAX forum created in 2008 free module for WiMAX. It is in C++ with open code: [1]. http://www.antd.nist.gov/seamlessandsecure/download.html
For NS2 is created module for VoIP too. Check them and you will have idea how to made in OPNET the same thinks.
Thanks Veneta for your support, But i need the application profile settings procedures for voice over P2P networks.
My suggestion was: If you check source of modules Ns2voip or Ns2voip++ (they are from 2010), you may modify these sources for P2P.
As far as I know there is not a specific application profile in OPNET for voice. In my opinion you have two options. The first one is to create an application profile that imitates voice creating not constant traffic but periodically with some randomness. It is easier than it sounds. The second and most interesting is to record a voice, (a telephone conversation for example) in two different audio files. Then, for each point of your P2P network you can read the data from the audio file (using C++ functions) end them through the network and store them in an end file. This way you can reproduce the audio, compare it with the initial and do a better study. However this second solution needs some programming but it will give you results that you can definitely publish.
In OPNET you have pre-defined voice application. Please take a look at the page 22 of the attached report.
