Abstract
Problem statement: For the purpose of supporting application services in the Ubiquitous Sensor Network (USN) environment, efficient processing of stream data that occur in the sensor nodes and relevant utilization technologies are being stu died. Approach: The conversion of various sensor stream data that occur in the sensor nodes into sen sor data suitable for use in the upper-level application system is required through sensing data monitoring by applying meta-database from the middleware on the server side. Results: In the earlier developed sensor data processing sy stem, unnecessary search and operation were performed from the middleware on the server side as for sensor stream data that occurred in the same sensor node o r in the similar area. Conclusion/Recommendations: In this study, sensing cache technique is used and efficient sensor data stream processing system is designed and built to reduce the redundant sensor d ata stream processing.
Highlights
With the development of Ubiquitous Sensor Network (USN) technology, necessary data for environmental monitoring, logistics surveillance, building management could be received through a wireless network from various small sensors
In a sensor network system currently being built, static metadata are stored by entering data directly on the server middleware, dynamic metadata are stored to the database of server middleware by collecting on periodic basis
This study proposed sensor stream data processing technique-Sensor Stream Cache Technique (S2CT) technique and S2CT system-which efficiently processed sensor data stream and excessively improved access to the database
Summary
With the development of Ubiquitous Sensor Network (USN) technology, necessary data for environmental monitoring, logistics surveillance, building management could be received through a wireless network from various small sensors. Data collected from sensor network come in the form of repetitive stream, it access database each data stream processing This type of database access is quite unnecessary in the nature of USN environment. Related research: A study on the data stream is actively underway in the field of the current international database Such interest recognized the need of efficiency of the DBMS for other areas in existing business areas through the development of the Internet. Such stream data processing technology is used to control real-time bank data management and provide intensive security services for the packet stream on the (Kawashima et al, 2006; Botts and Robin, 2007; Stonebraker et al, 2006) Internet.
