We analyzed the performance of Slotted-ALOHA in class. Do the similar analysis for Pure-ALOHA. That is, first find the probability of success by any node in terms of number of nodes (N) and probability of frame transmission (p). Then find p for which the probability of success frame transmission is maximized. What is the maximum value of the success probability when N

8. Why can't we detect collisions in wireless networks in wireless networks? Explain how does CSMA/CA work? Does CSMA/CA completely eliminate collisions? Why? (1+1+0.5+0.5 points) 9. We analyzed the performance of Slotted-ALOHA in class. Do the similar analysis for Pure-ALOHA. That is, first find the probability of success by any node in terms of number of nodes (N) and probability of frame transmission (p). Then find p for which the probability of success frame transmission is maximized. What is the maximum value of the success probability when N infinity? Draw a free hand sketch for Prob. of Successful frame transmission vs. p. Show the important points. (4 points)
