SMERT: energy-efficient design of a multimedia messaging system for mobile devices

Customized multimedia content delivery has become one of the most desirable applications to mobile device users. However its intense usage of wireless and user interfaces poses a great challenge to device usability and battery lifetime. In this paper, we describe our design and implementation of an energy-efficient multimedia messaging system to address this challenge. We construct a hierarchical system for users to access multimedia content, leveraging widely available short message service (SMS), an embedded system-based new interfacing device, and the Internet capability of mobile devices. Being the first of its type, the new system not only reduces energy overhead but also improves the usability of the service
