Assignment:
Consider the arrival scenario of Figure; the location of the packet arrival times arc permissible as shown under pure ALOHA, but not under slotted ALOHA, where arrivals are permitted only at the discrete times T,, where i = 0, 1 Assume that the average arrival rate is λ1.
(a) How would Figure need to be modified if slotted ALOHA is used? How would the pdfs of Nn and Nnchange?
(b) If user A's packet arrives at time Tn what is the probability of successful transmission?
Provide complete and step by step solution for the question and show calculations and use formulas.
