Pure ALOHA: The Unconstrained Approach

Pure ALOHA operates on a fundamental principle: a station can transmit data at any time it has data to sendWhat is the difference between pure Aloha and slotted There is no prior coordination or enforced schedule2024131—Key differences between Pure ALOHA and Slotted ALOHA ;Efficiency, Less efficient, More efficient; Throughput, Max 18.4% efficiency, Max 36.8%  This means Pure Aloha sends data anytime and any station has the freedom to transmit whenever the channel appears freeSlotted ALOHA improves throughput compared to pure ALOHAby introducing synchronization and reducing collisions, resulting in more efficient use of the  This approach offers simplicity and immediacy, allowing for instant transmission once a station has a packet readyWhat is Slotted ALOHA? In essence, time in Pure Aloha is continuous, and stations are not bound by any predefined temporal structuredifference between slotted aloha and pure aloha

However, this freedom comes at a significant cost202392—Time Slot, In Pure Aloha,any station can transmit data at any time. In Slotted Aloha, any station can transmit data only at the beginning of a  Because multiple stations can transmit simultaneously or with overlapping transmission times, the probability of collisions is inherently high A collision occurs when two or more stations attempt to transmit on the same channel at the same time, corrupting the data for all involvedDifferences between Pure Aloha and Slotted Aloha Consequently, Pure ALOHA allows stations to transmit whenever they want, leading to higher collision probabilityConsider the delay ofpure ALOHAversusslotted ALOHAat low load.
