Detailed Description

Keep track of the current position and velocity of an object.

All space coordinates in this class and its subclasses are understood to be meters or meters/s. i.e., they are all metric international units.

This is a base class for all specific mobility models.

Config Paths

ns3::MobilityModel is accessible through the following paths with Config::Set and Config::Connect:

  • /NodeList/[i]/$ns3::MobilityModel

Attributes

  • Position: The current position of the mobility model.
  • Velocity: The current velocity of the mobility model.

TraceSources

  • CourseChange: The value of the position and/or velocity vector changed

Member Function Documentation

int64_t ns3::MobilityModel::AssignStreams ( int64_t  stream)

Assign a fixed random variable stream number to the random variables used by this model. Return the number of streams (possibly zero) that have been assigned.

Parameters
streamfirst stream index to use
Returns
the number of stream indices assigned by this model

Definition at line 102 of file mobility-model.cc.

int64_t ns3::MobilityModel::DoAssignStreams ( int64_t  start)
privatevirtual

The default implementation does nothing but return the passed-in parameter. Subclasses using random variables are expected to override this.

Reimplemented in ns3::GaussMarkovMobilityModel, ns3::SteadyStateRandomWaypointMobilityModel, ns3::RandomWalk2dMobilityModel, ns3::RandomWaypointMobilityModel, and ns3::RandomDirection2dMobilityModel.

double ns3::MobilityModel::GetRelativeSpeed ( Ptr< const MobilityModel other) const
Parameters
otherreference to another object's mobility model
Returns
the relative speed between the two objects. Unit is meters/s.
