Abstract

Emergent information is created and utilized by an array of sensors. Each sensor is programmed with a trigger rule, which describes a local condition that must be met for the sensor to trigger an event signal, and a relationship rule, which describes a hierarchy of communication control among sensors in the array of sensors. When a predetermined percentage or weighting of the sensors trigger event signals, emergent information that describes conditions at the array location is generated.
