In a CSMA/CA scheme, a random delay is allowed whenever a collision occurs. What is the guarantee that future collision between previously collided terminals will not occur? Explain the rationale behind your answer.
What will be an ideal response?
CSMA/CA cannot guarantee that the future collisions will not occur due to the
nature of CSMA/CA. But it can reduce the future collisions by using back-off
scheme whenever a collision occurs. Because collision terminals randomly select
a back-off counter within the contention window, the future collisions can be
reduced but it is still possible that two or more terminals select the same back-off
counter so that there still exists a collision.
