Abstract
Automatic repeat request (ARQ) is very effective in error control, and among various ARQs, selective repeat gives the best throughput characteristics where infinite-capacity buffers are theoretically required in the transmitter and receiver stations. Therefore, in practice, a modified selective repeat request method with a finite-capacity buffer must be devised. In this paper, a selective repeat method is proposed where multiple frames corresponding to a message may continuously be sent. Based on the error rate, number of repeats, and round-trip delay time, the appropriate number of multiple transmissions for maximum throughput in the case of a finite-capacity buffer is derived. It is shown that good throughput characteristics can be achieved in the proposed method with an appropriate number of multiple transmissions. © 2001 Scripta Technica, Electron Comm Jpn Pt 1, 84(6): 68–76, 2001
