Set random position allocator for each simulation

[Matteo Bordin]

Hi,

I would like to set my node with random coordinates in a rectangle. Now I'm using

uemobility.SetPositionAllocator ("ns3::RandomRectanglePositionAllocator",

                                  "X", StringValue ("ns3::UniformRandomVariable[Min=0|Max=500.0]"),

                                  "Y", StringValue ("ns3::UniformRandomVariable[Min=0.0|Max=500.0]"));

but every time I run the simulation I get the same position.

eg. Every time I run the simulation, the first 2 nodes always have the following coordinates

x=470.743, y=183.2, z=0
x=376.579, y=230.287, z=0

What should I use to get different positions each time I run a simulation?

Pass --RngRun argument as described in https://www.nsnam.org/docs/release/3.33/manual/html/random-variables.html

So do I have to pass manually every time a different number as parameter for RngRun?
