   Feb 14, 2023 · Slotted ALOHA is a protocol that divides the channel into time slots and allows transmission only at the beginning of each slot. It reduces collisions and increases efficiency, but also increases delay and has low throughput.

   Pure Aloha can be termed as the main Aloha or the original Aloha. Whenever any frame is available, each station sends it, and due to the presence of only one channel for communication, it can lead to the chance of collision. In the case of the pure aloha, the user transmits the frame and waits till the receiver acknowledges it, if the receiver does...

   Slotted Aloha is simply an advanced version of pure Aloha that helps in improving the communication network. A station is required to wait for the beginning of the next slot to transmit. The vulnerable period is halved as opposed to Pure Aloha. Slotted Aloha helps in reducing the number of collisions by properly utilizing the channel and this basic...

   What is the difference between pure and slotted ALOHA?

   • The key idea behind the difference between pure and slotted Aloha is that shrinking the "window of vulnerability" during which a packet may suffer a collision around the beginning of its transmission is a way to improve efficiency.

   What is slotted ALOHA protocol?

   • The Slotted Aloha protocol has a maximum throughput of about 18.4%. This is because there is a significant risk of collisions when numerous nodes try to transmit at the same time, which causes missed packets and a decreased overall throughput.

   What is slotted ALOHA?

   • When less than or equal to 37% of the network’s total nodes are actively transmitting data, the maximum throughput is reached. Due to the high frequency of collisions, the throughput of Slotted Aloha is typically substantially lower than 18.4% in practice It is not a widely used protocol in today’s contemporary networks because of this.

    Slotted Aloha is a variation of "Pure" Aloha intended to improve performance by reducing the length of the window in time during which stations that start transmissions will collide. The idea is to divide time into slots each of which are just a bit longer than the packet transmission time and then, only allow stations to begin transmission of ...
