A Novel Method for Data Calibration in Wireless Sensor Networks
In order to provide efficient and suitable services for users in a ubiquitous computing environment,many kinds of context information technologies have been researched.Wireless sensor networks are among the most popular technologies providing such information.Therefore,it is very important to guarantee the reliability of sensor data gathered from wireless sensor networks.However there are several factors associated with faulty sensor readings which make sensor readings unreliable.The research put forward classifying faulty sensor readings into sensor faults and measurement errors,then propose a novel in-network data calibration algorithm which includes adaptive fault checking,measurement error elimination and data refinement.The proposed algorithm eliminates faulty readings as well as refines normal sensor readings and increase reliability.The simulation study shows that the in-network data calibration algorithm is highly reliable and its network overhead is very low compared to previous works.
