networking (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.
