Nodes group

The NODES (Networking in Open Distributed Environments) group has been formed at Department of Computer Science in University of Helsinki to stimulate and coordinate research on distributed and networked systems and applications. The current research focus lays on the design and development of infrastructure for mobile computing, on performance evaluation of distributed and networked systems, and on open distributed software architectures and services. We study how systems can be divided into independently working parallel parts, and how these parts communicate with each other.

The research projects co-ordinated by NODES can be further divided into four sub-groups: mobile computing and wireless data communication; open distributed systems; operating systems; and formal specification and verification. A new area, trust management, has started recently.

The First Ten Years of the NODES group is a book that covers the groups history under the name NODES until December 2004.
