Abstract:

When a data frame is lost or received corrupted during transmission, the solution adopted by the stop and wait protocol of the data-link layer is overtime retransmission. In this paper, we propose an improved algorithm by utilizing the correlation in quantum entanglement and instantaneous transmission of quantum teleportation. When something wrong happened during the data transmission, our algorithm sends negative frame and the acknowledgement frame instantaneously, which reduces the minimum time interval between two successful data frame transmission. Compared with the classical stop and wait algorithm, quantitative analysis illustrates that our algorithm improves the data frame transmission efficiency.
