I'm trying to implement a simplified version of the 802.11 DCF protocol. My question, is lets say there are multiple nodes waiting to transmit, each have a backoff counter associated with them. Now at the beginning, they each only wanted to transmit one packet, but over time during their back off, more packets started to enter the queue on node 11. It is now node 11's turn to transmit, does it transmit all the packets in its queue?
