Detailed Description
The basic RNG for NS-3.Note: The underlying random number generation method used by NS-3 is the RngStream code by Pierre L'Ecuyer at the University of Montreal.
NS-3 has a rich set of random number generators. Class RandomVariable defines the base class functionalty required for all random number generators. By default, the underlying generator is seeded all the time with the same seed value and run number coming from the ns3::GlobalValue RngSeed and RngRun.
