How can we identify the type of traffic in wireless communication?

Hi All,

If I want to create a traffic distribution for a service and need the traffic to be highly bursty, which inter-arrival time distribution should I use?

• Uniform distribution (0–180 ms)
• Pareto (mean: 6 ms, max: 12.5 ms)
• Exponential (mean: 180 ms)

Uniform distribution (0–180 ms)

That is obviously not bursty.

Exponential (mean: 180 ms)

First we need to calculate the multiplication factor that will give us a mean of 0.180. Then we model to see whether the result looks sufficiently bursty

t = 0:0.001:1;
syms f real
E = exp(f.*t);
F = double(vpasolve(mean(E) == 0.180))

F = -5.5438

TT = cumsum(exp(F.*rand(1,25)));
stem(TT,repmat(0.5,1,numel(TT)));

Well, it is a bit bursty, but I would not say it is satisfactory.

Pareto (mean: 6 ms, max: 12.5 ms)

Right at the moment, I am unsure of how to model that.
