On a wireless link,the probability of packet error is 0.2.A stop-and-wait protocol is used to transfer data across the link. The channel condition is assumed to be independent from transmission to transmission.What is the average number of transmission attempts required to transfer 100 packets?

The average number of transmissions to transmit n packets in S-W protocol with  error probability p is given by: n/(1-p).Hence,

Number of transissions =100/(1-0.2)
