Hi!
I am using the ns2HCCA patch to simulate ARROW scheduler using NS-2.27.
One thing is not clear to me, when calculating the txop of a stream,
should i use the minimum PHY rate specified in the TSPEC or should i call
the mac getDataRate() function which returns the data rate of the
physical layer.
Suppose i want to set my TXOP according to the Queue Size of the
stations and den want to poll each station for that much time.
What should my txop be:
1. Poll_overhead+SIFS+ACK+SIFS+(Queue_Size/Min_PHY_rate)
2. Poll_overhead+SIFS+ACK+SIFS+(Queue_Size/mac_->getDataRate())
Also, does anyone know the difference between backlog_ and queue_size_
define in the oneflow.cc file. Both correspond to the queue_size but
what exactly is the difference between the two?
Eagerly waiting for a response.
Thanks in advance
