[Ns-developers] EDCA and WifiRemoteStation

[Ramon Bauza]

Hello,

I would like to tell you something I have observed regarding the EDCA
mechanism and the WifiRemoteStation. I have realized that different packets
addressed to the same peer station contending for the medium at the same
time but enqueued in different AC queues share the same WifiRemoteStation.
This means that these packets share also the same m_slrc and m_ssrc
variables. Therefore, when an ACK is not received for a transmitted packet,
the common m_slrc variable would be incremented causing a reduction of the
transmission opportunities for the rest of the packets (destinated for the
same station but enqued in different AC queues).  Am I right about my
observation? If am not wrong, m_slrc and m_ssrc variables should be
considered per packet and not per peer station.

Thank you.
Best regards,
Ramon Bauza.
