Problem $2$

a$)$ A network with the following specifications:

Total Number of bits in the information frame including overhead bits $=5,000$ bits

Total Number of bits in the acknowledgment frame including overhead bits $=400$bits

Number of overhead bits in an info. or ACK frame $($address and CRC$)=300$ bits

Transmission bit rate $=1,000,000$bit$\frac{s}{s}$

Transmission delay $=1ms$

Frame processing delay $=2ms.$

Bit error probability $=3^{**}{10}^{-5}$

What will be the transmission efficiency if

i$)$ Go$-$Back$-4$ ARQ is used.

ii$)$ Stop$-$and$-$Wait ARQ is used.

b$)$ Compute the CRC code for the following sequence of bits $(10111011101)$ using the generating

polynomial $(10001).$
