Question

What does a CSMA/CA sender do when it first detects the medium idle after being busy ? Between 1-persistent, non-persistent, and p-persistent methods which has the highest probability of collision after the medium was sensed idle ? Token Passing is used on a topology with a single physical ring. What happens to the token when the station currently holding it breaks down ? What multiple access protocols do you think are better suited to provide Quality of Service in terms of bounded delay and capacity reservation ? The pure Aloha MAC (medium access control) protocol uses binary exponential backoff to

Explanation / Answer

it will transfer it immediately. Correct option is A.

8)

1 persistent has the highest probability of collision

9)

nothing, because of other nodes will have a larger reserve of tokens

10)

TDMA and CDMA/CA will be used

11)

enforce a random waiting time before a station retires transmission after the ACK timout expires.
