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. cannot check turn on fast startup

Aloha was designed for the wireless local area network (WLAN), which is also known as the radio broadcast. If more than one user transmits the data at the same time, then that data has a collision, and that data destroy. Type of Aloha WebThis is basically what happens in slotted ALOHA, just that you have individual transmission probabilities for you stations. You would not refer to the specified protocol as TDM (time division multiplexing), because the channel access is non-deterministic and non-repetitive, although you do have fixed time slots.
