Public Member Functions
virtual void	initialize (int stage)
	Initializes mobility model parameters.
Protected Member Functions
virtual void	handleSelfMsg (cMessage *msg)
	Called upon arrival of a self messages.
virtual void	beginNextMove (cMessage *msg)
	Begin new line segment after previous one finished.
virtual void	setTargetPosition ()=0
	Should be redefined in subclasses. This method gets called when targetPos and targetTime has been reached, and its task is to set a new targetPos and targetTime. At the end of the movement sequence, it should set targetTime=0.
Protected Attributes
simtime_t	targetTime
	end time of current linear movement
Coord	targetPos
	end position of current linear movement
Coord	stepTarget
parameters to handle the movement of the host
Coord	stepSize
	Size of a step.

Detailed Description

Base class for mobility models where movement consists of a sequence of linear movements of constant speed.

Subclasses must redefine setTargetPosition() which is supposed to set a new target position and target time once the previous one is reached.

NOTE: Does not yet support 3-dimensional movement.

Member Function Documentation

void LineSegmentsMobilityBase::initialize

(

int

stage

)

[virtual]

Initializes mobility model parameters.

Assigns a pointer to ConnectionManager and gets a pointer to its host.

Creates a random position for a host if the position is not given as a parameter in "omnetpp.ini".

Additionally the registration with ConnectionManager is done and it is assured that the position display string tag (p) exists and contains the exact (x) tag.

If the speed of the host is bigger than 0 a first MOVE_HOST self message is scheduled in stage 1

Reimplemented from BaseMobility.

Reimplemented in ANSimMobility, BonnMotionMobility, and TurtleMobility.
