WebWait ARQ method, Go back N method, and Selective-Repeat ARQ method. Often, the data link or transport layer of the ISO/OSI model uses these ARQ methods [4]. It is important to note that a reliable transport layer protocol such as TCP is needed for successful incorporation of ARQ and wireless data link protocols [4]. WebJan 6, 2024 · Selective Repeat Protocol. This protocol is almost like Go-Back-N ARQ protocol, or we can say that it is a modified form of GBN ARQ, the part where it differs is that here buffers are used and both receiver & sender maintain a window of size. This selective repeat works better at times when the network link is mostly unreliable.
