Accordingly, how throughput is improved in slotted Aloha?
The maximum throughput of Slotted ALOHA is 1 / 0.368 e = , which occurs at 1 G = ; this is doubled of that of Pure ALOHA. As we can see, the efficiency of Pure ALOHA can be improved by the introduced time slot structure. However, time synchronization is required to align stations to the slot structure.
Also, what is the efficiency of slotted Aloha? "A slot in which exactly one node transmits is said to be a successful slot. The efficiency of a slotted multiple access protocol is defined to be the long-run fraction of successful slots in the case when there are a large number of active nodes, each always having a large number of frames to send."
Similarly, you may ask, why is the throughput of slotted Aloha better than that of the pure Aloha?
The Slotted ALOHA is somewhat better than the Pure ALOHA. As the probability of collision is less in Slotted ALOHA as compared to Pure ALOHA because the station waits for the next time slot to begin which let the frame in a previous time slot to pass and avoids the collision between the frames.
What is the difference between Aloha and slotted Aloha?
The main difference between Pure ALOHA and Slotted ALOHA is that the time in Pure Aloha is continuous whereas, the time in Slotted ALOHA is discrete.
