Abstract
A method, apparatus, and computer program product are presented for detecting motion within an amorphous sensor node array. The operations performed include detecting an object at a node in the array, with a node that detects an object termed a 'detecting node'. Another operation includes sensitizing nodes about the detecting node to the possibility that the object will move toward the sensitized nodes. Still another operation includes, when the object moves toward a sensitized node, detecting the object at the sensitized node and propagating a warning signal to a distance from the sensitized node in the direction of the motion of the object. In another aspect, nodes are differentiated into a pattern comprising pattern elements, where each pattern element comprises at least one node, wherein the pattern is used to determine which nodes are sensitized about a detecting node and to determine a propagation direction for the warning signal.
