Aloha
     
         (From the Hawaiian greeting) A system of
        {contention resolution} devised at The {University of Hawaii}.
        {Packets} are {broadcast} when ready, the sender listens to
        see if they collide and if so re-transmits after a random
        time.  {Slotted Aloha} constrains packets to start at the
        beginning of a time slot.  Basic Aloha is appropriate to long
        propagation time nets (e.g. satellite).  For shorter
        propagation times, {carrier sense} {protocols} are possible.
