Sensor-Cloud Infrastructure - Physical Sensor Management with Virtualized Sensors on Cloud Computing

Increasing numbers of physical sensors are used for various purposes. Those physical sensors are usually used by their own applications. Because each application manages both of physical sensors and their sensor data exclusively, other applications cannot use the physical sensors in the different party easily. We propose a new infrastructure called Sensor-Cloud infrastructure which can manage physical sensors on IT infrastructure. The Sensor-Cloud Infrastructure virtualizes a physical sensor as a virtual sensor on the cloud computing. Dynamic grouped virtual sensors on cloud computing can be automatic provisioned when the users need them. The approach to enable the sensor management capability on cloud computing. Since the resource and capability of physical sensor devices is limited, the cloud computing on the IT infrastructure can be behalf of the sensor management such as availability and performance of physical sensors. This paper describes the design of Sensor-Cloud Infrastructure, the system architecture and the implementation.
