WebJan 7, 2024 · How does ALOHA protocol work? ALOHA is a multiple access protocol for transmission of data via a shared network channel. In ALOHA, each node or station transmits a frame without trying to detect whether the transmission channel is idle or busy. If the channel is idle, then the frames will be successfully transmitted. WebThe term Aloha in computer network means hello. Aloha is a data-link layer multiple access protocol that describes how multiple terminals can access the medium without interfering or conflicting.
