Problem
i. Explain the binary exponential back-off algorithm of CSMA/CD scheme.
ii. Then assuming TWO(2) CSMA/CD stations are trying to transmit a BIG file. After each frame is sent, they contend for the channel using binary exponential back-off algorithm. What is the probability that the contention ends on round k, and what is the mean number of rounds per contention period? Calculate first few terms to get the approximated answers.
