Suggestions for Test 2:

• 1) For the OLSR protocol, consider a specific network topology, and determine the multipoint relays of the various hosts.

  Similar to the above question on OLSR, try to understand the behavior of other protocols such as DSR and AODV by using example networks.

• 2) For the various TCP optimizations, assume that a certain packet is lost on the wireless link, and try to plot a "packet trace" that shows when various events occur. Determine whether the sender will reduce its congestion window or not, under a variety of delay values for the wireless links.
• 3) For rate control MAC protocol, try to recreate the example discussed in class to show how the rate chosen by a sender host changes with time, as a function of transmission success and failures.
• 4) What are the functions to be performed by various entities when executing Mobile IP protocol? (such as home agent, foreign agent, etc.).
