Abstract
Described is a method for event localization within a distributed sensor array using a plurality of sensor nodes. The method includes an act of receiving a signal in at least one detecting node. The signal originates from an external disturbance and has a local signal such that the local signal reflects a relative proximity (i.e., between the detecting nodes) to the external disturbance. The method also includes acts of exchanging information regarding the signal between the detecting node and nearby nodes; and localizing the external disturbance based on its relative proximity. Through receiving a signal that reflects a relative proximity to the external disturbance and exchanging that information between nearby nodes, the sensor array localizes the external disturbance.
