Q45

The values of parameters for the Stop-and-Wait ARQ protocol are as given below: Bit rate of the transmission channel $= 1$ Mbps. Propagation delay from sender to receiver $= 0.75$ ms. Time to process a frame $= 0.25$ ms. Number of bytes in the information frame $= 1980$. Number of bytes in the acknowledge frame $= 20$. Number of overhead bytes in the information frame $= 20$. Assume there are no transmission errors. Then, the transmission efficiency (expressed in percentage) of the Stop-and-Wait ARQ protocol for the above parameters is _____________ (correct to $2$ decimal places).
