In this animation, the data requirements of the nodes change as they move through the area. The network state is shown from the point of view of 4 different units. In each case, the unit owning the display is shown in light blue. The dashed boxes show individual data query; the cooperatively computed group queries are shown as solid boxes. As the nodes move, their individual queries change to reflect their current locations. New groups are formed, groups merge, and group queries change as the nodes move. The temporary query and data inconsistencies are typical of operation in challenging communication environments.
