12.8 SPECIFYING NODE MOBILITY
Any WLAN node can be either xed or mobile. Fixed nodes remain stationary
throughout the simulation, while mobile nodes can move around as the simulation
progresses. You can specify the movement of the node during simulation via attribute
trajectory, which contains a list of preset movement trajectories. If needed, you can
specify your own trajectory of the node movement through the Topology> Dene
Trajectory… menu option or clear the deployed trajectory through the Topology >
Clear Trajectory Assignment… option.
