The objective of the paper is to propose a privacy model for ubiquitous healthcare system involving unconventional information sources like laboratory scanning equipments, networked computing systems and distributed wireless sensors using an actor based domain specific approach. In the existing privacy models for ubiquitous healthcare systems the trust on the middleware and the deployed security mechanisms...
We focus on the part of disseminating context information to enable context awareness in various users, devices, and applications, and hence enabling context-based applications in heterogeneous environments such as ambient networks. By making the network itself context-aware, significant contributions are being made in heterogeneous environments. Our `Pure Overlay Space' based context dissemination...
The dissemination of context information to enable context-awareness in various users, devices, and applications is a focus of current research in mobile network computing. The aim of our overall research is to build a balanced, adaptable, and interoperable overlay-based context dissemination mechanism for next generation networks. Our pure overlay space architecture acts as a base for the development...
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...
Ambient Networks enable co-operation between heterogeneous networks, on demand, in order to provide ubiquitous connectivity to end-users. Incorporating contexts for such networking systems in a loosely coupled fashion, though challenging, yields futuristic results. ContextWare is a model for context processing which acquires and distributes context data among interested context entities. In this paper,...
CSON-D is a novel overlay-based context dissemination system which aids in enabling network users and applications to be context-aware and supports all types of context information. The dissemination protocol is appropriate for autonomous systems in heterogeneous and dynamic environments. Developing and maintaining context-aware efficient systems in such environments, our overall objective, is a challenging...
