The fundamental idea behind Slotted ALOHA is to mitigate the inefficiencies of Pure Aloha by synchronizing transmissions作者：D JIA·2018·被引用次数：12—We employ signaturecodesto help the receiver identify the packets contained in collisions, and use successive interference cancellation (SIC)  In Pure Aloha, a station can transmit a packet at any time, leading to a higher probability of collisionsCoded ALOHA for Massive Random Access Slotted ALOHA, on the other hand, divides the channel's time into fixed-length slots, where each slot is precisely the time it takes to transmit one packetRandom Access Protocols - ALOHA, CSMA, CSMA/CA and A station wishing to transmit a packet must wait for the beginning of an available slot to initiate its transmissionNumerical Problems Related To Pure Aloha and Slotted This synchronization significantly reduces the chance of two packets colliding2021911—Aloha is a packet switching system. The time interval required to transmit one packet is called aslot.Alohais a random access technique. If two or more stations attempt to transmit in the same slot, a collision occurs, and all involved stations must retransmit their packets after a random backoff periodNear-far effect on coded slotted ALOHA
