Improvement of slotted aloha as

The original version of the protocol (now called Pure ALOHA, and the one implemented in ALOHAnet) was quite simple: • If you have data to send, send the data • If, while you are transmitting data, you receive any data from another station, there has been a message collision. All transmitting stations will need to try resending later.
