Analysis of Research Trends in Retransmission Techniques in Data Communications

In data communications, data retransmission mechanisms are essential to ensure reliable data transmission. In this paper, we analyze various data retransmission algorithms and recent research trends. Traditional algorithms such as ACK and timeout-based retransmission, NACK-based retransmission, and selective repetition are reviewed, and modern retransmission techniques utilizing machine learning and network coding are discussed. These techniques contribute to increasing adaptability to the network environment and maximizing the efficiency of data transmission. This work highlights the importance of retransmission mechanisms in ensuring the reliability of data communication and provides directions for future research.
