Ambient Networks enable co-operation between heterogeneous networks, on demand, in order to provide ubiquitous connectivity to end-users. We focus on the part of disseminating context information to enable context-based applications (for e.g., resource update and management) and systems in ambient and ubiquitous networks. Our pure overlay space architecture acts as a base for the development and maintenance of application-layer context-aware dissemination protocols. Our multi-level overlay network based dissemination protocol exhibits dynamic and fair context dissemination. In this paper, we first overview this 'pure overlay' and 'multi-level overlay' combined context dissemination scheme and discuss its constraints in autonomous and heterogeneous environments. We then focus on proposing techniques for improving this dissemination scheme towards ubiquitous networking which satisfies our goals with regard to creating a user-friendly data model. The proposed optimizations include: local transformations, personalized extensions, and hybrid customizations. This paper is complemented with case study evaluation and simulation study results.
