Abstract: With the development of wireless sensor network technology,it is widely used in many fields,like the military and national defense,industry and agriculture,urban management,biomedical,environmental monitoring,disaster relief.Due to the wireless sensor network nodes characteristics,its data storage and query strategy have become a hot research.In this paper,the existing data storage strategies were described in detail and researched,and their strengths and weaknesses were analyzed.Following by the combination of big data,an efficient data storage structure-RCFile was applied to the data stored in the sensor network.The data structure was changed though combining the row-store and co-lumn-store.Based on RCFile,a data storage algorithm was proposed named wireless sensor network data storage based on RCFile (WDSR),and then the corresponding results of the analysis were given.The simulation results show that the proposed algorithm has certain advantages in low power and high efficiency.Finally,the trend of the future development of wireless sensor data storage and query strategy research networks was given.
