Consider sender’s sliding window size in Go - Back - n ARQ is equal to sender’s window size in Selective Repeat ARQ. Which of the following expression represents the relation between Go - Back - n and selective repeat ARQ in terms of n? (Where n is number of bits that are used to represent frame sequence number)
1
2n + 2n - 1 = 1
2
2n – 2n - 1 = 2
3
2n - 1 – 2n = 1
4
2n + 1 – 2n = 2
