1. A method for event detection utilizing data from a multiplicity of sensor sources which includes: deploying a plurality of sensor sources to provide sensor detections for an area of interest; identifying groups of deployed sensor sources as expected sensor sequences of possible interest, each identified sensor sequence being indicative of an event and including a plurality of sensor sources; identifying expected time differences between sensor detections from sensor sources in each identified sensor sequence; operating upon receipt of a sensor detection from a first sensor source to identify all sensor sequences which include said first sensor source; operating upon receipt of one or more additional sensor detections from one or more additional sensor sources other than said first sensor source, comparing the receipt times between the sensor detections from each sensor source included in said first and additional sensor sources with the expected time differences between sensor detections in each identified sensor sequence containing said first and additional sensor sources; and when said receipt times match said expected time differences for an identified sensor sequence, identifying the event indicated by said identified sensor sequence.
