ARQ Review and Modifications
C. T. Bhunia · IETE Technical Review · 2001
In Computer and Data communication network, error is controlled by the basic three ARQ techniques that are Stop and Wait ARQ, Go-Back-N ARQ and Selective Repeat Request ARQ. One of the important measures of peformance of the techniques is throughput. In order to achieve higher throughput, a number of modifications of basic ARQ techniques are suggested in literature those include Sastry's modification, Morris's modification, Weldon's modification and recent Chakraborty's modification. In this paper a thorough review of the techniques have been done. Based on the critical review, we have suggested four important modifications that lead to achieve higher throughput and to tackle the dynamic channel and the error of feedback path.
