Sensor device virtualization for mobile cloud systems

Mobile services can be characterized by wireless transmission and sensor data, so typical mobile cloud systems include additional servers which are not found in the traditional cloud systems. “Push/Sync” servers are examples to enhance wireless network experience, but no server can be found to aid the delivery of sensor data. As a result, developers have to write code to access sensor data using their own protocols under the error-prone wireless network, which makes the development time longer. To address this issue, we propose a mobile sensor device virtualization scheme that allows developers to access sensor data using local (cloud-side) sensor APIs instead of network APIs even if the services are run on cloud servers. Therefore, it is much easier to develop mobile services.
