Please then write (with your own words) the ONE-PAGE summary of the paper. Problem 3 Two CSMA/CD stations are trying to transmit a few long video les. After each frame is sent, they contend for the channel using binary exponential back-o algorithm. What is the probability that the contention ends on round k, and what is the mean number of rounds per contention period? Please calculate rst few terms to get the approximated answer. Problem 4 Review the CSMA/CA-based 802.11 protocols for Wireless Local-Area Networks (WLAN). Ex-plain the dierences among 802.11a, 802.11b and 802.11g. Also explain the back-o algorithm with the 802.11 protocols....
