If the device prepares to transmit and finds the link busy, it waits until is no longer busy,
and then waits a backoff_time as follows:
backoff_time = Min Retry Time + random(Max Retry Time - Max Retry Time )
and transmit. If the device has a collision in transmission the device tries again,up to a
configurable number of retries (
