The NODES unit (Networking in Open Distributed Environments) coordinates collaboration between distributed systems and telecommunication research groups.  The focus areas are networked systems and their enablers: interoperability (e.g., service and software platforms, interoperability management, contracting, trust management, privacy), mobility (technology and location independence, wireless computing), information networks, service networks, context awareness and ubiquitous computing. The research groups combine the departmental tradition of wireless and mobile computing to new research themes. The focus of the groups is in transition from platform protocols to solving application layer challenges.
