Patent ID: 7948373

Claim:
A method for reducing power consumption of sensors provided for sensing conditions within a sensor network comprising the steps of: a central controller receiving sensor data comprising current sensed condition data transmitted from a plurality of different sensors; said central controller calculating a correlation between said plurality of different sensors on the basis of the received sensor data and calculating a transmission schedule for said sensors on the basis of a correlation between sensor data comprising sensed condition data transmitted from said plurality of different sensors to the central controller, wherein the transmission schedule is made up of time periods, such that sensors with a high correlation having a correlation coefficient exceeding a predetermined adjustable threshold value do not transmit sensor data to said central controller during the same time period and wherein sensors without a high correlation transmit sensor data to the central controller substantially during the same time period; and wherein the central controller assigns transmission periods to each sensor for transmitting sensor data to said central controller according to the calculated transmission schedule.
