Application-level FEC implementation in ns-3?

[Amita Kamath]

Dear All,

Is there an implementation of application-level FEC available in ns-3? We have searched the documentation, but we are only able to find FEC in the context of WiMAX and the physical/MAC layers.

If not, is there any library interfaced with ns-3 that we could use for this purpose instead?

Thanks and regards,

Hi,

the channel errors (and the FEC techniques) are simulated statistically in ns-3. There is no bit-level simulation, only a chunk-level one (study the spectrum model).

What you can do is to add the proper overhead in the packets (for the FEC bits) and modify the error probability functions according to your needs, or you could add a residual error probability (it's not modeled in ns-3) and work with that one at application level.

Thank you very much for your reply, Mr. Pecorella. We will certainly look into the solutions you suggested.
