WebFeb 14, 2024 · Pure ALOHA refers to the original ALOHA protocol. The idea is that each station sends a frame whenever one is available. Because there is only one channel to share, there is a chance that frames from different stations will collide. The pure ALOHA protocol utilizes acknowledgments from the receiver to ensure successful transmission. WebRoberts [16] introduced slotted ALOHA, which requires senders to transmit at the beginning of time slots established by clock synchronization at the physical layer. The key advantage of slotted ALOHA is that it doubles the maximum throughput attainable with pure ALOHA. This is the result of reducing the time during which a data packet is vulnerable

WebSlotted ALOHA was invented to improve the efficiency of pure ALOHA as chances of collision in pure ALOHA are very high. In slotted ALOHA, there is still a possibility of collision if two stations try to send at the beginning of the same time slot. Slotted ALOHA still has an edge over pure ALOHA as chances of collision are reduced to one-half.
