aloha - Computer Definition
From the Hawaiian aloha, meaning hello and goodbye. Also known as pure Aloha. A protocol developed at the University of Hawaii in the early 1970s as a contention management mechanism for use in inter-island wireless networks. Aloha is a very simple protocol in which the source just sends a frame of data whenever it desires. A target receiver confirms a frame whenever it receives one, and the source sends another whenever it desires. If the target receiver does not confirm the receipt of the frame within a specified time, the source resends it until it receives a confirmation. Pure Aloha is simple and inexpensive, but not useful in managing contention in large, complex networks. See also AlohaNet and slotted Aloha.
A type of TDMA transmission system developed by the University of Hawaii used for satellite and terrestrial radio links. In the traditional ALOHA system, packets are transmitted as required, and, like Ethernet's CSMA/CD method, collisions can occur. A "Slotted ALOHA" system triggers transmission starts by a clock and reduces the number of collisions.
