Automatic Repeat-Request Courseware

Abstract

An Automatic Repeat Request (ARQ) courseware is demanded from the teacher for the course IIA0502 “Basics of Computer Networks”. A java applet is the target of this design. The user interface must give the user freedom to select necessary parameters, simulate Stop-and-wait, Go-Back-N, Selective Repeat ARQ data transfer process, show the result, allow students have more intuitive understanding of the ARQ theory. Although this ARQ simulation courseware is not perfect running, some bugs are exist, still those simulation results could meet the theory
