Dec 18, 2014 at 2:09 Add a comment 1 Usually, the Poisson distribution is chosen because the process is assumed to be memoryless. Suppose that a packet just arrived.

WebALOHA: it is used to transmit data in a shared medium. In this, multiple stations will be transmitting data at the same time. this leads to collision and hence the data will not be clear and are very difficult to understand. This concept is used in random acess protocol and therefore it does not belong to channelization protocol. WebDec 17, 2024 · The simplest version of ALOHA is called slotted ALOHA.
