Patent ID: 7496477

Claim:
A method for monitoring values generated by one or more sensor devices in a pervasive sensor environment, said sensor device for generating actual sensor data values, said method comprising: receiving, at a computing node in communication with each said one or more sensor devices, actual sensor data values at varying time instants, and, in response to received actual sensor data value, said computing node computing a sensor value range for communication to said individual sensor device; generating, by a predictor element at each said one or more individual sensor devices, a new predicted sensor value based on past sensor values, and a predicted sensor value range at said sensor device based on said new predicted sensor value; determining, at each said one or more individual sensor devices, whether a new actual data sample is outside each respective predicted sensor value range for that respective individual sensor device; and, one of: implicitly updating said predictor element at said individual sensor device using said new predicted sensor value if said new actual data sample value falls within said predicted precision sensor value range without communicating said new actual data sample to said computing node; or, transmitting said new actual data sample to said computing node, and updating, by said computing node, said predictor element at said individual sensor device based on said new actual data sample, whereby a total amount of communication between said computing node and said sensor devices is reduced.
