The critical characteristic here is that time is considered continuousIn summary, while bothprotocolsaim to manage access to a shared medium,Slotted ALOHAimproves efficiency and reduces collisions by introducing time slots for  However, this freedom comes at a cost作者：S SURYAVANSH·2018—(3.5) shows thecomparisonof throughput vs traffic offered forpureandslot- tedALOHA protocols. As evident from the figure, maximum throughput forslotted. The primary challenge with Pure Aloha is the high probability of frame hitting, leading to collisionsUnlikepure aloha, aslotted alohawould disallow data transmission when the station is willing to send it. The shared channel in aslotted alohagets divided  When two or more stations transmit their frames close enough in time that their transmission windows overlap, the data becomes corrupted, and retransmission is necessaryThe maindifference between Pure ALOHA and Slotted ALOHAis that the time inPure Alohais continuous whereas, the time inSlotted ALOHAis discrete. The efficiency of Pure Aloha is notoriously low, with a theoretical maximum efficiency of only 18What are the two types of Aloha?4%Difference Between Pure ALOHA and Slotted ALOHA This means that even under ideal conditions, less than a fifth of the channel's capacity can be effectively utilizedThe maindifference between Pure ALOHA and Slotted ALOHAis that the time inPure Alohais continuous whereas, the time inSlotted ALOHAis discrete. This limitation makes Pure Aloha less suitable for modern networks demanding higher throughputSLOTTED ALOHAIt was developed just to improve the efficiency ofpure alohaas the.

To address the inherent inefficiencies of Pure Aloha, the Slotted Aloha protocol was developedALOHA Protocol in Computer Networks Explained Simply The fundamental innovation in Slotted Aloha is the division of time into discrete, equal-sized intervals known as time slots作者：S SURYAVANSH·2018—(3.5) shows thecomparisonof throughput vs traffic offered forpureandslot- tedALOHA protocols. As evident from the figure, maximum throughput forslotted. This protocol introduces structure by stipulating that data can be transmitted at the beginning of the time slotSLOTTED ALOHAIt was developed just to improve the efficiency ofpure alohaas the. This seemingly minor change has a profound impact on network performancePure-and-Slotted-Aloha-System.pdf By synchronizing transmissions to the start of these slots, the vulnerable period during which collisions can occur is significantly reducedPure-and-Slotted-Aloha-System.pdf In Slotted Aloha, a station willing to send data must wait for the beginning of the next available slotPure ALOHAis a classical random accessprotocolwhere nodes can transmit data frames at any time. In contrast,Slotted ALOHAdivides time into discrete slots  This disallows data transmission immediately as it becomes available, unlike in Pure AlohaIn summary, while bothprotocolsaim to manage access to a shared medium,Slotted ALOHAimproves efficiency and reduces collisions by introducing time slots for 

The direct consequence of this slotting mechanism is a substantial reduction in collisionsPure ALOHAis a classical random accessprotocolwhere nodes can transmit data frames at any time. In contrast,Slotted ALOHAdivides time into discrete slots  When stations adhere to the slot boundaries, the overlap window for transmissions is halved compared to Pure AlohaALOHA in Computer Network - Scaler Topics This drastic reduction in collisions leads to a doubling of the peak throughputAs we can see, the efficiency ofPure ALOHAcan be improved by the introduced timeslotstructure. However, time synchronization is required to align stations  The efficiency of Slotted Aloha is theoretically higher than its predecessor, with its maximum efficiency also expressed as G x e, but it achieves a significantly better peak throughputillustrates the comparison of throughput performance While the exact figures can vary based on implementation and parameters like the multiple access channel allocation, Slotted Aloha is generally considered to be about twice as efficient at its peak compared to Pure AlohaALOHAprovides a wireless data network.
