Q. 47 The values of parameters for the Stop-and – Wait ARQ protocol are as given below.
Bit rate of the transmission channel = 1Mbps Propagation delay from sender to receiver = 0.75 ms Time to process a frame = 0.25ms 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 that 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 place) .
