Data synchronization between adjacent user devices for personal cloud computing

This paper describes ad hoc data synchronization among devices for sharing contents. The purpose of this paper is to share user data in heterogeneous environments, without depending on central server. This technology can be applied to synchronize personal data between a device and a personal cloud storage for personal cloud services. The ad hoc synchronization needs sync agent service discovery module, user authentication module, network adapter, and application data synchronization module. The method described in this paper is better than existing synchronization technology based on client-server in availability, performance, and scalability quality attributes.
