Efficient Sensor Stream Data Processing System to use Cache Technique for Ubiquitous Sensor Network Application Service
Recently, 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. With the development of these technologies, various types of sensors were used in USN environments and sensor data generated from the nodes also changed very complicated. Metadata is defined and used in order to define the information of these sensor nodes. While such a large amount of metadata generated from the network, it is a cause to increase the data transmitted from sensor nodes.
