Abstract
A major concern in data communications is the effective and efficient control of transmission errors caused by channel noise so that error-free data can be delivered to the user. In view of this concern, to achieve error-free data, various Data Link Layer error-control schemes were proposed. Automatic-repeat-request (ARQ) schemes and Hybrid ARQ (HARQ) have been considered.
