Difference between pure aloha and slotted aloha

Aloha is one of the fundamental protocols in LAN and WAN networks. This carrier sense multiple access (CSMA) protocol is used in local area networks and is especially useful in situations where many devices share the same channel and want to communicate with each other. There are two basic forms of aloha: pure aloha and slotted aloha. The main differences between both types of aloha are explained below.

1. Pure Aloha:

Pure aloha is the original shape of the Carrier Sense Multiple Access (CSMA) protocol and is the simplest form of aloha. Pure aloha allows any device share the channel equally, which means that Devices can transmit at any time. However, this also means that devices can transmit at the same time, which can cause collisions.

2. Slotted Aloha:

Slotted aloha is an improved version of pure aloha, which divides time into discrete time slots or intervals. Transmissions are scheduled in these slots, which reduces the probability of collisions and increases system efficiency. Slotted aloha is most often used in satellite network systems.

In summary, the main difference between pure aloha and slotted aloha is:

Pure Aloha allows any device to share the channel equally, meaning devices can stream at any time.
Slotted aloha divides time into discrete time slots or intervals, reducing the probability of collisions and increasing system efficiency.

In conclusion, both types of aloha remain useful in different situations and are essential in communication and access sharing in local area networks. Now that you know the differences between pure aloha and slotted aloha, you can choose the one that best suits your needs.
