Abstract—As an emerging portable service platform, OSGi is now taking a more and more important role in constructing a ubiquitous computing system. Since ubiquitous computing system is always a distributed system, people may face many challenges such as heterogeneous devices communication and vulnerable wireless network. This paper proposes a solution for constructing such a system based on LIR-OSGi and R2-OSGi. With the help of both frameworks, the system can treat any devices as service as well as cope with network exceptions automatically and transparently. This paper also introduces a demo system of smart house to prove our solution for the ease of use. Through this solution, any type of network devices can be connected to the network while the communication between devices remain robust.

Index Terms—Ubiquitous Computing, OSGi, Middleware, LIR-OSGi, R2-OSGi.
