nOStrum

Ubiquitous computing aims at dynamically supporting users in everyday life with applications on mobile devices in the surroundings. Component frameworks, such as OSGi™(1), ease the dynamic management of such application software. Yet, OSGi focuses on Java, while many mobile devices only support native languages with reasonable performance. This project presents nOStrum(2), the first native OSGi implementation. Our C++ prototype conforms to the OSGi R4 specification and runs without any modifications on standard POSIX systems with support for ELF binaries. It provides the core functionality of the OSGi module, life cycle and service layer in a native C++ environment. We measured considerable improvements of performance and memory consumption in comparison to common Java OSGi frameworks. Successful tests on various platforms, such as x86, x64, Sun SPARC and ARM demonstrate the portability of nOStrum.
