WebSlotted Aloha There is a high possibility of frame hitting in pure aloha, so slotted aloha is designed to overcome it. Unlike pure aloha, slotted aloha does not allow the transmission of data whenever the station wants to send it. In slotted Aloha, the shared channel is divided into a fixed time interval called slots. WebFeb 14, 2024 · Read Discuss Slotted ALOHA is an improved version of the pure ALOHA protocol that aims to make communication networks more efficient. In this version, the channel is divided into small, fixed-length time slots and users are only allowed to transmit data at the beginning of each time slot.
