Detailed Description

Linear movement model. See NED file for more info.

This mobility module expects a torus as playground ("useTorus" Parameter of BaseWorldUtility module).

NOTE: Does not yet support 3-dimensional movement.

Member Function Documentation

void LinearMobility::fixIfHostGetsOutside

(

)

[protected, virtual]

Should be redefined in subclasses.

Should invoke handleIfOutside() and pass the references to the parameters to be modified.

Additional action after border handling (such as choosing a new target position if the BorderPolicy is PLACERANDOMLY) should be implemented here.

HandleIfOutside

Reimplemented from BaseMobility.

Definition at line 56 of file LinearMobility.cc.

References angle, BaseMobility::handleIfOutside(), stepTarget, BaseWorldUtility::use2D(), BaseMobility::world, and BaseMobility::WRAP.

    Coord dummy(world->use2D());
    handleIfOutside(WRAP, stepTarget, dummy, dummy, angle);

void LinearMobility::makeMove

(

)

[protected, virtual]

Move the host.

Move the host if the destination is not reached yet. Otherwise calculate a new random position

Reimplemented from BaseMobility.

Definition at line 67 of file LinearMobility.cc.

References acceleration, angle, fixIfHostGetsOutside(), Move::getSpeed(), Move::getStartPos(), Coord::getX(), Coord::getY(), Coord::info(), Move::info(), BaseMobility::move, Move::setDirectionByTarget(), Move::setSpeed(), Move::setStart(), Coord::setX(), Coord::setY(), stepTarget, and BaseMobility::updateInterval.

{
  debugEV << "start makeMove " << move.info() << endl;

    move.setStart(stepTarget, simTime());

    stepTarget.setX(move.getStartPos().getX() + move.getSpeed() * cos(PI * angle / 180) * updateInterval.dbl());
    stepTarget.setY(move.getStartPos().getY() + move.getSpeed() * sin(PI * angle / 180) * updateInterval.dbl());

    move.setDirectionByTarget(stepTarget);

    debugEV << "new stepTarget: " << stepTarget.info() << endl;

    // accelerate
    move.setSpeed(move.getSpeed() + acceleration * updateInterval.dbl());
