Rajeev:
NodeXL is intended for static graphs (with some simple user interactions) and doesn't support WPF's animation features. You could try a brute-force animation that uses a timer to periodically move a vertex and redraw the graph. That might work for small graphs, but I'm sure it wouldn't perform well for larger graphs.
If you simply want to highlight a node in a static manner, you could select it (assuming you are using the NodeXLControl), or make its color, size, or shape different from the other vertices.
