Detailed Description

Steady-state random waypoint mobility model.

This model based on random waypoint mobility (RWM) model for case when speed, pause and position are uniformly distributed random variables. The difference is that the initial values of this parameters are not from uniform distribution but from stationary distribution of RWM model. The implementation of this model is 2d-specific and with nonzero nodes speeds.

Based on NS-2 implementation by Toilers Research Group – Colorado School of Mines (http://toilers.mines.edu). The papers related to this code are: W. Navidi and T. Camp, Stationary Distributions for the Random Waypoint Mobility Model, IEEE Transactions on Mobile Computing, vol. 3, no. 1, pp. 99-108, January-March 2004. W. Navidi, T. Camp, and N. Bauer, Improving the Accuracy of Random Waypoint Simulations Through Steady-State Initialization, Proceedings of the 15th International Conference on Modeling and Simulation (MS '04), pp. 319-326, March 2004.

Member Function Documentation

int64_t ns3::SteadyStateRandomWaypointMobilityModel::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 from ns3::MobilityModel.

Definition at line 277 of file steady-state-random-waypoint-mobility-model.cc.

References ns3::RandomVariableStream::SetStream().

Vector ns3::SteadyStateRandomWaypointMobilityModel::DoGetPosition ( void ) const

privatevirtual

Returns: the current position.

Concrete subclasses of this base class must implement this method.

Implements ns3::MobilityModel.

Definition at line 256 of file steady-state-random-waypoint-mobility-model.cc.

Vector ns3::SteadyStateRandomWaypointMobilityModel::DoGetVelocity ( void ) const

privatevirtual

Returns: the current velocity.

Concrete subclasses of this base class must implement this method.

Implements ns3::MobilityModel.

Definition at line 272 of file steady-state-random-waypoint-mobility-model.cc.

void ns3::SteadyStateRandomWaypointMobilityModel::DoInitialize ( void )

protectedvirtual

This method is called only once by Object::Initialize. If the user calls Object::Initialize multiple times, DoInitialize is called only the first time.

Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject and AggregateObject from within this method.

Reimplemented from ns3::Object.

Definition at line 96 of file steady-state-random-waypoint-mobility-model.cc.

References ns3::Object::DoInitialize().

void ns3::SteadyStateRandomWaypointMobilityModel::DoSetPosition ( const Vector & position )

privatevirtual

Parameters

position the position to set.

Concrete subclasses of this base class must implement this method.

Implements ns3::MobilityModel.

Definition at line 262 of file steady-state-random-waypoint-mobility-model.cc.
