Random Variable Distributions
[Core]

Collaboration diagram for Random Variable Distributions:

Classes

class  ns3::RandomVariable
 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. More...

class  ns3::UniformVariable
 The uniform distribution RNG for NS-3.

This class supports the creation of objects that return random numbers from a fixed uniform distribution. It also supports the generation of single random numbers from various uniform distributions. More...

class  ns3::ConstantVariable
 A random variable that returns a constant

Class ConstantVariable defines a random number generator that returns the same value every sample. More...

class  ns3::SequentialVariable
 Return a sequential list of values

Class SequentialVariable defines a random number generator that returns a sequential sequence. The sequence monotonically increases for a period, then wraps around to the low value and begins monotonicaly increasing again. More...

class  ns3::ExponentialVariable
 Exponentially Distributed random var

This class supports the creation of objects that return random numbers from a fixed exponential distribution. It also supports the generation of single random numbers from various exponential distributions. More...

class  ns3::ParetoVariable
 ParetoVariable distributed random var

This class supports the creation of objects that return random numbers from a fixed pareto distribution. It also supports the generation of single random numbers from various pareto distributions. More...

class  ns3::WeibullVariable
 WeibullVariable distributed random var

This class supports the creation of objects that return random numbers from a fixed weibull distribution. It also supports the generation of single random numbers from various weibull distributions. More...

class  ns3::NormalVariable
 Class NormalVariable defines a random variable with a normal (Gaussian) distribution.

This class supports the creation of objects that return random numbers from a fixed normal distribution. It also supports the generation of single random numbers from various normal distributions. More...

class  ns3::EmpiricalVariable
 EmpiricalVariable distribution random var

Defines a random variable that has a specified, empirical distribution. The distribution is specified by a series of calls to the CDF member function, specifying a value and the probability that the function value is less than the specified value. When values are requested, a uniform random variable is used to select a probabililty, and the return value is interpreted linerarly between the two appropriate points in the CDF. The method is known as inverse transform sampling: (http://en.wikipedia.org/wiki/Inverse_transform_sampling). More...

class  ns3::IntEmpiricalVariable
 Integer-based empirical distribution

Defines an empirical distribution where all values are integers. Indentical to EmpiricalVariable, except that the inverse transform sampling interpolation described in the EmpiricalVariable documentation is modified to only return integers. More...

class  ns3::DeterministicVariable
 a non-random variable

Defines a random variable that has a specified, predetermined sequence. This would be useful when trying to force the RNG to return a known sequence, perhaps to compare NS-3 to some other simulator More...

class  ns3::LogNormalVariable
 Log-normal Distributed random var

LogNormalVariable defines a random variable with log-normal distribution. If one takes the natural logarithm of random variable following the log-normal distribution, the obtained values follow a normal distribution. This class supports the creation of objects that return random numbers from a fixed lognormal distribution. It also supports the generation of single random numbers from various lognormal distributions. More...

class  ns3::GammaVariable
 Gamma Distributed Random Variable

GammaVariable defines a random variable with gamma distribution. More...

class  ns3::ErlangVariable
 Erlang Distributed Random Variable

ErlangVariable defines a random variable with Erlang distribution. More...

class  ns3::ZipfVariable
 Zipf Distributed random var (between 1 and n included). More...
class  ns3::TriangularVariable
 Triangularly Distributed random var

This distribution is a triangular distribution. The probablility density is in the shape of a triangle. More...

class  ns3::RngStream
 Combined Multiple-Recursive Generator MRG32k3a. More...
