Hi. I have to simulate an IEEE 802.11 scenario with both DCF (802.11-legacy) and EDCA (802.11e) stations; adhoc topology should suffice.
I searched for this at http://www.isi.edu/nsnam/ns/doc/node193.html and I quickly looked at related ns-2 examples in cvs. It looks like 802.11e (EDCA) is not supported (and so there is no possibility to simulate a mixed DCF/EDCA scenario). I know about the out-of-tree ns-2 802.11e patch at http://www.tkn.tu-berlin.de/research/802.11e_ns2/ but as far as I know it does not let you simulate both DCF and EDCA stations in the same scenario. I also looked at ns-3 wifi model http://www.nsnam.org/doxygen-release/index.html It looks like QoS and non-QoS MACs (i.e. EDCA and DCF) are well integrated in ns-3. Even if I didn't test it, it should be possible to simulate a mixed DCF/EDCA scenario in ns-3. Do you know if it is possible to simulate a mixed DCF/EDCA in ns-2? Any comments are welcome. Cheers, Luca Favatella
