Comparison between Automatic Repeat Request (ARQ) Protocols and solving the Buffer Problem

Today is the era of fast and dynamic internet and communication technologies which make communication convenient compared to the past. Communication technology, through different channels, such as mobile phones and computers, has become pervasive. In almost every means of telecommunication, retransmission protocols have played a significant role in the protocol stack layers. The primary aim of this study is to compare Automatic Repeat Request (ARQ) protocols and solve the Buffer problem. The first section compares ARQ protocols (Go-Back-N, selective repeat, stop and wait ARQ), using TCP and UDP. The study compares these protocols' efficiency and changes the behaviors of stop and wait protocols to selective repeat. The second section includes solving the buffer problems. The paper contains the theoretical part as well.
