a. Compare between ALOHA and slotted ALOHA by discussing the pros and cons of each. b. Justify the need for reliable delivery service at the data link layer given that this can be achieved at the transport layer by implementing TCP. c. Assume a wired LAN network with bus topology and the length of the cable is 1 Km. A total of 100 devices connected to the bus, with each node transmitting large number of frames, and the capacity of the link is 10 Mbps. The data link layer generates a maximum frame size of 512 bytes, with the signal propagating at speed of 3X108 m/s. i. ii. Calculate the efficiency of CSMA/CD in this network. Explain the impact of increasing frame size on protocol efficiency. Justify your answer. d. Assume a node detected a collision while accessing the channel in CSMSA/CD. The node will then wait random time (K *512 bit times) before accessing the channel again. Calculate the waiting time in ms for the node given that the random number generated is K-100 for 10 Mbps Ethernet. e. List two examples of taking turn protocols. a.
