[Ns-developers] Contribution - DVB-RCS DAMA Implementation in NS-2.32

[Francesco Zampognaro]

Dear all,

I created a set of changes to NS-2.32 in order to run transport
protocols over a simulated DVB-RCS satellite environment with DAMA
(Demand Assignment Multiple Access) on the return link.

It is different from the already present contribution in
http://nsnam.isi.edu/nsnam/index.php/Contributed_Code named "TDMA DAMA"
in using different selectable allocation algorithms and offering the
possibility of mixing request strategies. Behaviour matches paper [1].

Work is still necessary to define a better MAC layer and to read
DropTail queue status without the use of additional bound variables (see
backlog_ in the patch), but the contribution is already perfectly
working.

Pointer to the patch, installation guide and test script are here:
http://www.tlcsat.uniroma2.it/DAMA/

Some details on the implementation can be found here:

Any advice is welcome...

Thanks!

Francesco Zampognaro.
