Jeder Benutzer kann jederzeit in einen dieser Slots senden. On the other hand, Slotted ALOHA was introduced by Roberts in In pure ALOHA, whenever a station has data to send it transmits it without waiting whereas, in slotted ALOHA a user wait till the next time slot beings to transmit the data. In pure ALOHA the time is continuous whereas, in Slotted ALOHA the time is discrete and divided into slots. Slotted ALOHA. Computer Network Computer Engineering MCA. ALOHA is a medium access control (MAC) protocol for transmission of data via ashared network channel. Using this protocol, several data streams originating from multiple nodes are transferred through a multi-point transmission channel. There are two types of ALOHA protocols – Pure ALOHA and Slotted ALOHA. Slotted Aloha divides the time of shared channel into discrete intervals called as time slots. Any station can transmit its data in any time slot. The only condition is that station must start its transmission from the beginning of the time slot. Slotted ALOHA Protocol was invented to improve the efficiency of pure ALOHA as chances of collision in pure ALOHA are very high. Though there is still a possibility of collision if two stations try to send data at the beginning of the same time slot. Slotted Aloha. 1. In this aloha, any station can transmit the data at any time. In this, any station can transmit the data at the beginning of any time slot. 2.

Aloha in computer networks is an access control protocol. Pure Aloha in networking allows the stations to transmit the data at anytime.
ALOHA ist daher wie die meisten Funkprotokolle nicht echtzeitfähig, da nicht garantiert werden kann, wann ein zu sendendes Paket tatsächlich erfolgreich übertragen wird.
Each time slot corresponds to the length of the frame. The Slotted ALOHA makes the station to wait till the next time slot begins and allow each data frame to be transmitted in the new time slot.
Synchronization can be achieved in Slotted ALOHA with the help of a special station that emits a pip at the beginning of every time slot as a clock does.
This collision cause frame overloading and the frame are destroyed. When the frame has damaged the stations, have to wait for the random amount of type, and when the frame is free, the transmission is done successfully.
There is a waiting time of each frame and when the waiting time is transmitting data the size of the frame should be random.
Waiting time of frames should not be the same as it can cause data collisions. It allow each frame to be achieved with the help of special frames.

Wenn der Rahmen die Stationen beschädigt hat, müssen Sie auf die zufällige Menge des Typs warten, und wenn der Rahmen frei ist, wird die Übertragung erfolgreich durchgeführt.
