Hi Ittipong, Thank you so much for your time. I have gone through the B-MAC paper. As per my knowledge, it does the following.
When a packet is scheduled to be transmitted, it checks the CCA and transmits the packet only if the channel is free. Else it takes a random back-off and tries to send later. But I don't want to transmit/receive any packet. I just want to know whether the channel is empty or not. Thanks again.
