Understanding the Slotted ALOHA Protocol

In a slotted ALOHA system, time is divided into fixed-length time slotsNotes ALOHA All stations are synchronized, and transmissions are only permitted to begin at the start of a slot202371— Efficiency (E) The formula for efficiency is given by E=Ge−2G. where G=pN. Slotted ALOHA Efficiency (E) The efficiency formula isE=Ge−G. The fundamental principle behind slotted ALOHA is that if two or more stations transmit within the same slot, a collision occurs, and their data may be lost results and the analytical result of the throughput and the collision probability, of infinite-station slotted ALOHA obtained from Equations.S = G e − G. This differs from Pure ALOHA, where stations can transmit at any time, leading to a higher probability of overlapping transmissions and thus more frequent collisionsSlotted Aloha - an overview | ScienceDirect Topics
