Method Detail

getInitialLocation

public Coord getInitialLocation()

Returns a possible (random) placement for a host

Specified by:

getInitialLocation in class MovementModel

Returns:

Random position on the map

getPath

public Path getPath()

Description copied from class: MovementModel

Returns a new path by this movement model or null if no new path could be constructed at the moment (node should wait where it is). A new path should not be requested before the destination of the previous path has been reached.

Specified by:

getPath in class MovementModel

Returns:

A new path or null

replicate

public RandomWaypoint replicate()

Description copied from class: MovementModel

Creates a replicate of the movement model.

Specified by:

replicate in class MovementModel

Returns:

A new movement model with the same settings as this model

randomCoord

protected Coord randomCoord()
