Location is a fundamental service for mobile computing. Typical GPS receivers, although widely available for navigation purposes, may consume too much energy to be useful for many applications. Observing that in many sensing scenarios, the location information can be post-processed when the data is uploaded to a server, we design a cloud-offloaded GPS (CO-GPS) solution that allows a sensing device...
Following rising demands in positioning with GPS, low-cost receivers are becoming widely available; but their energy demands are still too high. For energy efficient GPS sensing in delay-tolerant applications, the possibility of offloading a few milliseconds of raw signal samples and leveraging the greater processing power of the cloud for obtaining a position fix is being actively investigated. In...
In real-time playing of network audio-video, because of delay and dithering, effective data caches processing and audio-video synchronization control must be carried out to resume time connection among data. A scheme of using DataSet to process data in caches is proposed. Synchronous control method of thread and arithmetic of audio-video synchronization playing are discussed in detail. The new scheme...
