Study on fuzzy prediction systems over sensor data streams

To utilize the current data on sink to response to users' queries in time, this paper adopts pyramid time model to maintain the aggregation values at different time over sensor data streams, and a fuzzy prediction system is built with these aggregation values. With predictive values made by the fuzzy prediction system, users' queries can be answered in time. Due to the prediction method introduced, new observation data don't need transmit to sink immediately, thus nodes can save energy.
