Specified by:

replicate in class MovementModel

Returns:

A new movement model with the same settings as this model

nextPathAvailable

public double nextPathAvailable()

Description copied from class: MovementModel

Returns a sim time when the next path is available. This implementation returns a random time in future that is MovementModel.WAIT_TIME from now.

Overrides:

nextPathAvailable in class MovementModel

Returns:

The sim time when node should ask the next time for a path
