- Context-aware Communication Control
This sub-project investigates mechanisms for context-aware communication control of Nexus applications. Due to latent discrepancies between an application's requirements and the capabilities of heterogeneous mobile communication networks, communication patterns of Nexus applications such as the visualization of spatial-world model information must be adaptive and cross-layer optimized. Therefore, one major focus of this project are network-based mechanisms for adaptive transport of model data. The other principal work item are context-aware adaptation control and orchestration methods spanning several application instances. The methods to be developed will use high-quality context information from the Nexus world model, in addition to model-based access network discovery and selection, which has already been investigated in the first funding period.
- Security, Privacy and Accounting in Context-Aware Systems
The target of the sub-project is to ensure the acceptability of context-aware systems by means of technical mechanisms, considering the divergent requirements of users, content and service providers. The research program includes adaptive protection and privacy mechanisms as well as means to enable accounting of context-aware services. The security mechanisms shall be context-aware, they shall have a fine granularity, and they target on open system platforms in environments that are only partly trustworthy. Finally, the developed mechanisms shall be integrated into a multilateral security solution.
