NetSim Packet Animator animates packet flow in addition to node movement. Since packets may be generated very often(in intervals of micro seconds) whereas node movement happens once in every second(m/s) it might not be possible to identify node movement quickly.
1. Ensure that velocity in the node general properties is non-zero. In WSN the velocity of the sensor nodes are initally set to 0 m/s by default. You may have to modify this to see some movement in the animator.
2. In the packet animator, before starting the animation, increase the animation speed to the max by moving the slider to the right extreme:
3. In case of MANET, in the application configuration, just for you to initially visualize and understand node movement in NetSim animator, you could try decreasing the frequency of packet generation by increasing the inter-arrival-time to 1 or 2 Seconds (1000000/2000000 micro seconds) :
