Major automatic repeat request protocols generalization and future develop direction

In the error control system, in order to ensure the validity and reliability of data transmission, people usually use error control. Automatic retransmission request (ARQ), which restores error messages by requesting receivers to send error data messages again is a method for processing channel errors in communication system. There are three basic ARQ ways, stop and wait ARQ (SW), Go back N ARQ (GBN), and Selective repeat ARQ (SR). This paper illustrates the coding classification types, their advantages and disadvantages, then points out the improvement direction on applications in the future based on ARQ's defects. In addition, this paper also explains each ARQ applications and their latest research results. Due to previous studies, there is no completed research of ARQ's classifications and their corresponded applications, therefore, this paper would give a simplified comprehension of ARQ.
