How does slotted aloha work

WebIn slotted aloha, successful data transmission takes place only when each slot individually transmits only a single data frame. By doing this collision probability reduces to a large extent. If no data packet is transmitted in any of the slots, then it will remain idle. http://web.mit.edu/modiano/www/6.263/lec10.pdf
