CHAPTER 11

ALOHANET CASE STUDY

  1. Why would TDM or FDM have been inefficient for it?

    2. Because messages from mobile/subscriber announcing its presence is quite short and infrequent, poor utilization of channels is not a problem (problem that is covered with TDM and FDM).

  2. Would polling be a feasible option?

    3.  

     

  3. How would you improve the Aloha protocol?

    4.  

     

  4. Can you think of a way to gain the flexibility of Aloha random access while still using the channel efficiently?
