eyeDentify: Multimedia Cyber Foraging from a Smartphone

The recent introduction of smartphones has resulted in an explosion of innovative mobile applications. The computational requirements of many of these applications, however, can not be met by the smartphone itself. The compute power of the smartphone can be enhanced by distributing the application over other compute resources. Existing solutions comprise of a light weight client running on the smartphone and a heavy weight compute server running on, for example, a cloud. This places the user in a dependent position, however, because the user only controls the client application. In this paper, we follow a different model, called cyber foraging, that gives users full control over all parts of the application. We have implemented the model using the Ibis middleware. We evaluate the model using an innovative application in the domain of multimedia computing, and show that cyber foraging increases the application's responsiveness and accuracy whilst decreasing its energy usage.
