A Time Eficient Approach for Detecting Errors in Big Sensor Data on Cloud

A Time Eficient Approach for Detecting Errors in Big Sensor Data on Cloud A Time Ef?cient Approach for Detecting Errors in Big Sensor Data on Cloud. Big sensor data is prevalent in both industry and scienti?c research applications where the data is generated with high volume and velocity it is dif?cult to process using on-hand database management tools or traditional data processing applications. Cloud computing provides a promising platform to support the addressing of this challenge as it provides a ?exible stack of massive computing, storage, and software services in a scalable manner at low cost. Some techniques have been developed in recent years for processing sensor data on cloud, such as sensor-cloud. However, these techniques do not provide ef?cient support on fast detection and locating of errors in big sensor data sets. For fast data error detection in big sensor data sets, in this paper, we develop a novel data error detection approach which exploits the full computation potential of cloud platform and the network feature of WSN. Firstly, a set of sensor data error types are classi?ed and de?ned. Based on that classi?cation, the network feature of a clustered WSN is introduced and analyzed to support fast error detection and location. Speci?cally, in our proposed approach, the error detection is based on the scale-free network topology and most of detection operations can be conducted in limited temporal or spatial data blocks instead of a whole big data set.
