"Predict-Revise" Data Management Method for Wireless Sensor Networks of Monitoring
Maoqing Li · Journal of Xiamen University · 2010
The data management techniques of wireless sensor networks(WSN) are summarized into four categories,i.e.,declarative language,signal processing,model prediction,and middleware.This paper describes the key of moving the traditional data management techniques to WSN,and considers the constraints of power consumption and band width limit at the mean time.For the WSN of monitoring,a new Predict-Revise data management method is proposed.It creates one virtual table for each measurement variable of sensor nodes,and combines all the tables into a virtual database.After approaching reading,prediction,revise,the system will get the result with higher accuracy.An experiment for monitoring the temperature of lab is presented to verify this new method.
