Welcome to the home page for The Global Distributed Diary.

The project is support by the Research Council of Norway, Distributed IT Programme (DITS), grant no. 112577/431 and 119400/431. Founding has also been received from ESPRIT IV through cooperation with the Moby Dick project (LTR 20422).

The project is founded om three projects:

These projects have their own project pages as well.

Project summary

The GLOBAL DISTRIBUTED DIARY project is an experimental project aimed at gaining knowledge of how systems can support integration of mobile nodes, and how distributed applications can be built that behave properly under the very variable conditions that may occur in such integrated systems.

The project has two main scientific goals. First, to address and devise solutions to the data consistency problems that arises when small, personal, variably connected mobile machines are integrated into an infrastructure for data sharing dominated by stationary, well connected computers. Second, to devise a distributed application (a distributed diary), along with appropriate system support (which includes security), that handles consistent read/write sharing of replicated data between a large set of heterogeneous, variably connected computers.

The GLOBAL DISTRIBUTED DIARY is used as our research vehicle, and has few scientific merits per se. However, by exploiting the possibilities provided by the GLOBAL DISTRIBUTED DIARY, a wide range of problems can be investigated.

See this page for an extended project descrition of the GDD project.
