UbiNet: A Generic and Ubiquitous Service Provider Framework

In mobile environment, it is very common that mobile devices periodically stay in disconnection mode. In a networked world as today, computer users rely on network services so heavily that even a short duration of disconnection from network will dramatically distract user's normal activity. Past researches explored disconnected operation for file system and database access. In this paper, we introduce and evaluate a ubiquitous network service framework. The proposed framework combines the advantages of both disconnection operation and system virtualization in order to provide 7/24 services to mobile users. We implemented and validated our idea in both Linux and Windows platform. From our initial deployment and daily usage experiment, our architecture is highly feasible and deployable. In this paper, we will illustrate the architecture, implementation, and performance evaluation based on our implemented system.
