Communication and filtering of events among peer controllers in the same spatial region of a sensor network

摘要

In a wireless tag identification and processing architecture and infrastructure, a method and system that eliminates redundant reporting and processing of the same event observed by different reader/sensors. Reader/sensors and their respective connected controllers are configured as peers when they observe or cover the same spatial region. When an event is observed within the spatial region, the first controller to receive the event data reports the electronic tag data and event data to the next higher processing domain and to its peer controllers. Then when the same electronic tag data or other event data indicating that a subsequent event is actually the same event as observed earlier is received by another peer controller, the another peer controller does not report nor process the electronic tag data and other event data to the next higher processing domain or to its peer controllers.
