An particular person solely can ship information firstly of the dialog; a actual time exists, that ranges between few seconds by which the movement ought to full.

The Slotted ALOHA makes the station to wait till the next time slot begins and allow each data frame to be transmitted in the new time slot.

Merge this question into. The waiting time of the each station must be random and it must not be same just to puree the collision of the frames again and again.
