الحصول على السعرaggregate value computed at the sink at any instant should be accurate to within ±R. In other words, the application is assured that, if the value reported by the sink is V, the true value of the aggregate state (which would require each sensor to report each sample to the sink) lies within [V −R,V +R]. The sensor network itself is modeled as
