Detailed Description

Random direction mobility model.

The movement of objects is based on random directions: each object pauses for a specific delay, chooses a random direction and speed and then travels in the specific direction until it reaches one of the boundaries of the model. When it reaches the boundary, it pauses, selects a new direction and speed, aso.
