Abstract:

Eco-hydrological Wireless Sensor Network in the Heihe River Basin can be considered as a successful application of wireless sensor network technology in the field of near-surface observation.This paper introduces a quality control approach for a wide variety and long-time massive data,especially for Heihe WSN observation data.Owing to the potential sources of systematic errors of wireless sensor network,there are some quality problems of the WSN data.Therefore,an adequate data quality control technique is of great importance.Firstly,the spatial and physical characteristics of WSN data were analyzed,and the definitions and implementation algorithms of WSN data quality elements were put forward as well.The algorithms involved timeliness and consistency assessment,data fragmentation processing,outlier detection,data redundancy processing,etc.Furthermore,there were two quality assessment cases were provided,and each one consisted of appropriate amounts of quality elements algorithms.The cases demonstrated that the proposed approach has the advantage of high efficiency and reasonable result,and played a vital role in the assignment of quality control for Heihe WSN observation Data.

Key words: Heihe river, WSN, Automatic observation, Quality assessment, Quality element
