Il in both cases ia around
1024 bytes. Is it beacues of cbr packet size.
Also if i want to keep the throughput between two nodes as 500Kbps, 1000Kbps,
1500Kbps and finally as 2000Kbps what parameters should i look for?

Hi
I have not been able to understand what does we mean by synchronization of cbr
flow and why does it happen. Any Comments.

Hi
In mac802.11 one of the state the system can enter is idle state. We have a
three variable rx_state_ , tx_state and nav_. Can anybody tell how can we
calculate the the idle time before the station enters either in transmit or
receive mode.
