Path Generation for Mobility Models by Diffusion

This applet demonstrates the generation of "reasonable" paths between
waypoints. These paths are typically employed in conjunction with
suitable speed models for simulating user mobility. The resulting mobility models
find their application in the analysis of wireless network performance.

In order to compute a path towards a particular waypoint
a virtual source of gas is placed at this waypoint. After
a virtual diffusion process is computed, a path from any other
position is found by following the steepest gradient of the
concentration.

Left-click to a position within the layout to place the gas source.

After a few seconds the concentration will be computed.
Then right-click to the position where the path shall originate from.
