Abstract

Energy consumption of wireless data communications on mobile devices is growing due to the increase in mobile data traffic caused by the popularity of mobile Internet applications. To address this issue, we propose CasCap, a novel cloud-assisted context-aware power management framework, which takes advantage of the processing, storage and networking resources in the cloud to provide secure, low-cost and efficient power management for mobile devices. CasCap is featured by crowd-sourced context monitoring, functionality offloading to the cloud, and providing adaptations as services. We give three example scenarios where wireless data communications are adapted to network conditions, traffic characteristics and location information. Our preliminary results show the potential of using CasCap to improve energy efficiency in wireless data communications.
