Hi, I am trying to disable congestion and initial backoff for my project using mica2 with CC1000 radio(Tinyos 1.x). I have set the values of backoff to 0 in the initialBackoff and congestionBackoff functions in CC1000RadioIntM. But this is not resolving the issue. The node which is supposed to transmit later is still doing carrier sensing and transmitting after the first node has finished transmission. Is it because the second node is in RX_STATE mode and it goes to TX_STATE after it finishes receiving the packet? What I want to achieve is that when a node has a packet to send,it does not sense whether the channel is busy and sends the packet immediately. If it is currently receiving a packet, it discards it and sends its own packet.
How can I do that? Thanks in advance! Debo
