Explain briefly about selective repeat arq

Webc) Suppose a network using the Selective Repeat ARQ protocol with m = 3, the values of variables are Sf = 21, Sn = 24, and Rn = 22 where the forward channel is unreliable, and the reverse is the opposite. WebNov 10, 2009 · ARQ transmits ACK one by one while Block ACK transmits many ACKs at a time. In this paper, ARQ, as the object of comparison, is a Stop and Wait-type ARQ. Since the sequence and number of transmission is determined by Master, we used simple ARQ rather than using more complicated ones, such as sliding window-type, Go-back-N or …
