Laying the Foundation for Pervasive Computing

A context-sensitive dynamic role-based access control model for pervasive computing environments

Resources and services are accessible in pervasive computing environments from anywhere and at any time. Also, due to ever-changing nature of such environments, the identity of users is unknown. However, users must be able to access the required resources based on their contexts. These and other similar complexities necessitate dynamic and context-aware access control models for such environmen...

A semantic-aware role-based access control model for pervasive computing environments

Access control in open and dynamic Pervasive Computing Environments (PCEs) is a very complex mechanism and encompasses various new requirements. In fact, in such environments, context information should be used in access control decision process; however, it is not applicable to gather all context information completely and accurately all the time. Thus, a suitable access control model for PCEs...

A Roadmap to the Introduction of Pervasive Information Systems in Healthcare

Pervasive healthcare is an emerging research discipline, which focuses on the development of pervasive and ubiquitous computing technology for healthcare environments. Information and Communication Technologies have dramatically evolved during the last decade, laying a solid foundation for the future generation of Ubiquitous Internet access. As a result, current efforts in research and developm...

Fractal social organization as a foundation to pervasive social computing services

Pervasive social computing is a promising approach that promises to empower both the individual and the whole and thus candidates itself as a foundation to the “smarter” social organizations that our new turbulent and resource-scarce worlds so urgently requires. In this contribution we first identify those that we consider as the major requirements to be fulfilled in order to realize an effecti...
