The Core Concept of Slotted ALOHA

At its heart, Slotted ALOHA operates by dividing the shared communication channel's time into discrete, fixed-length intervals known as time slotsThe Slotted ALOHA protocoldivides the time interval into discrete slots, each of which is equal to one frame's worth of time. To avoid collisions, this  This fundamental division is a key differentiator from Pure ALOHAThe Flowchart of The ST-Slotted-CS-Aloha Proposed In Pure ALOHA, a station could transmit at any moment it had data, leading to a higher probability of frame collisionsCoded Slotted ALOHA A Graph-Based Method for By introducing time slots, Slotted ALOHA imposes a synchronization requirement: stations can only transmit their data at the beginning of a time slotSlotted Aloha This structured approach significantly mitigates the chances of two or more frames overlapping and collidingWhat is slotted aloha?

The underlying principle is that if two or more frames are transmitted in the same time slot, a collision occurs2020923—In case ofslotted ALOHA, the vulnerable time period for collision between two frames is equal to time duration of 1 slot, which is equal to 1  However, the vulnerable period for collision between two frames is reduced to the duration of a single slotFileDiagramma di flusso Slotted ALOHA.png This is a critical improvement over Pure ALOHA, where the vulnerable period extends for the entire duration of a frameThe protocol was later improved with slotted ALOHA, which divides time into discrete slots to reduce collision probability and improve efficiency.

While various implementations and theoretical models exist, the general slotted aloha flowchart depicts a clear operational sequenceSlotted ALOHA Presentation | PDF A common representation shows a node attempting to transmitALOHA Protocol Overview and Flowchart | PDF If the node has data to send, it waits for the next available time slotThe protocol was later improved with slotted ALOHA, which divides time into discrete slots to reduce collision probability and improve efficiency. Upon entering a slot, transmission occursSlotted ALOHAis an improved version of Pure ALOHA that divides time into fixed-length slots, allowing data to be sent only at the start of a slot,  If other nodes also transmit in the same slot, a collision is detectedDifferences between Pure and Slotted Aloha In such a scenario, the frames involved are lost, and the transmitting nodes typically employ a backoff mechanism, retransmitting their data in a subsequent, randomly chosen slot after a delayWeek1 Study Slotted ALOHA
