Chapter 6, Problem P12P
a.
Explanation of Solution
The formula to calculate the efficiency for pure and slotted ALOHA is:
%calculating efficiency of slotted aloha
efficiencySA = (N * p .*(1 - p ).^(N - 1));
%calculating efficiency of pure aloha
efficiencyPA = (N * p .* ((1 - p).^(2*(N - 1))));
The below
Program:
%Give value for N
N = 15;
%Give linspace
p = linspace(0.001, 0.999, 200);
%calculating efficiency of slotted aloha
efficiencySA = (N * p ...
b.
Explanation of Solution
The formula to calculate the efficiency for pure and slotted ALOHA is:
%calculating efficiency of slotted aloha
efficiencySA = (N * p .*(1 - p ).^(N - 1));
%calculating efficiency of pure aloha
efficiencyPA = (N * p .* ((1 - p).^(2*(N - 1))));
The below program is used to find the efficiency for Pure ALOHA and slotted ALOHA for the value “N = 25”.
Program:
%Give value for N
N = 25;
%Give linspace
p = linspace(0.001, 0.999, 200);
%calculating efficiency of slotted aloha
efficiencySA = (N * p ...
