Question
What is the efficiency of slotted
aloha?Solution
Efficiency of Slotted Aloha Efficiency of Slotted Aloha (η) = G x e-G where G = Number of stations willing to transmit data at the beginning of the same time slot For maximum efficiency, We put dη / dG = 0 Maximum value of η occurs at G = 1 Substituting G = 1 in the above expression, we get- Maximum efficiency of Slotted Aloha = 1 x e-1 = 1 / e = 0.368 = 36.8% Maximum Efficiency of Slotted Aloha (η) = 36.8%
