Fidelity-Aware Replication for Mobile Devices

Mobile devices often store data in reduced resolutions or custom formats in order to accommodate resource constraints and tailormade software. The Polyjuz framework enables sharing and synchronization of data across a collection of personal devices that use formats of different fidelity. Layered transparently between the application and an off-the-shelf replication platform, Polyjuz bridges the isolated worlds of different data formats. With Polyjuz, data items created or updated on high-fidelity devices—such as laptops and desktops—are automatically replicated onto low-fidelity, mobile devices. Similarly, data items updated on low-fidelity devices are reintegrated with their high-fidelity counterparts, when the application permits it. Polyjuz performs these fidelity reductions and reintegrations as devices exchange data in a peer-to-peer manner, ultimately extending the eventual-consistency guarantee of the underlying replication platform to the multi-fidelity universe.

In this paper, we present the design and implementation of Polyjuz and demonstrate its benefits for a fidelity-aware contacts management application.
