The ALOHA protocol is a fundamental method used for managing access to a shared communication channel, particularly in network environments where multiple users or devices need to transmit data over the same medium. The primary purpose of ALOHA is to handle the challenge of collisions—situations where multiple devices attempt to send data simultaneously, leading to interference and data loss. There are two main types of ALOHA: • Pure ALOHA: Devices transmit data whenever they have it to send, and if a collision occurs, they wait for a random period before attempting to retransmit. • Slotted ALOHA: The time is divided into discrete slots, and devices are required to transmit only at the beginning of these slots, reducing the chance of collisions compared to Pure ALOHA.
