Detailed Description

UwGMPosition class implements the Gauss Markov 3D mobility model.

Constructor & Destructor Documentation

◆ UwGMPosition()

UwGMPosition::UwGMPosition ( )

Constructor of UwGMPosition class.

References alpha_, alphaPitch_, debug_, directionMean_, pitchMean_, updateTime_, xFieldWidth_, yFieldWidth_, and zFieldWidth_.

◆ ~UwGMPosition()

UwGMPosition::~UwGMPosition ( )

virtual

Destructor of UwGMPosition class.

Member Function Documentation

◆ command()

int UwGMPosition::command	(	int	argc,
		const char const	argv
	)

virtual

TCL command interpreter. It implements the following OTcl methods:

Parameters

argc	Number of arguments in argv.
argv	Array of strings which are the command parameters (Note that argv[0] is the name of the object).

Returns: TCL_OK or TCL_ERROR whether the command has been dispatched successfully or not.

References bound_, HARDWALL, REBOUNCE, speed_, speedMean_, SPHERIC, and THOROIDAL.

◆ Gaussian()

double UwGMPosition::Gaussian ( )

private

Method that returns a value from a normal random Gaussian variable (zero mean, unitary viariance)

Referenced by update().

◆ getX()

double UwGMPosition::getX ( )

protectedvirtual

Returns the current projection of the node on the x-axis. If it's necessary (updating time ia expired), update the position values before returns it.

Returns: The new x-axis position value of the node.

References nextUpdateTime_, and update().

Here is the call graph for this function:

◆ getY()

double UwGMPosition::getY ( )

protectedvirtual

Returns the current projection of the node on the y-axis. If it's necessary (updating time ia expired), update the position values before returns it.

Returns: The new y-axis position value of the node.

References nextUpdateTime_, and update().

Here is the call graph for this function:

◆ getZ()

double UwGMPosition::getZ ( )

protectedvirtual

Returns the current projection of the node on the z-axis. If it's necessary (updating time ia expired), update the position values before returns it.

Returns: The new z-axis position value of the node.

References nextUpdateTime_, and update().

Here is the call graph for this function:

◆ update()

void UwGMPosition::update ( double now )

privatevirtual

Method that updates both the position coordinates as function of the number of states to be evaluated.

References alpha_, alphaPitch_, bound_, debug_, direction_, directionMean_, Gaussian(), HARDWALL, nextUpdateTime_, pitch_, pitchMean_, REBOUNCE, speed_, speedMean_, SPHERIC, THOROIDAL, updateTime_, vx, vy, vz, xFieldWidth_, yFieldWidth_, and zFieldWidth_.

◆ updateTime_

double UwGMPosition::updateTime_

protected

Defines the behaviour of the node when it reaches the edge: SPHERIC: return in the simulation field on the opposite side THOROIDAL: return in the centre of simulation field HARDWALL: the movement is stopped in the edge REBOUNCE: the node rebounce (i.e., the movement that should be outside the simulation field is mirrored inside) Time between two update computation.
