Pure ALOHA

Pure ALOHA is a basic method for devices to communicate over a shared network. Devices send their messages whenever they want, without checking if the channel is free. If two devices transmit at the same time, their messages clash and become unreadable. To handle this, devices wait a random time before trying again, reducing the chance of collision. This simplicity makes Pure ALOHA easy to implement, but it’s not very efficient, especially when many devices are communicating at once, leading to more message conflicts and retransmissions.
