Adaptation to Connectivity Loss in Pervasive Computing Environments
نویسندگان
چکیده
Pervasive computing environments aim at providing users with advanced services, dynamically composed our of networked services. In these open environments, availability of specific networked service instances cannot be guaranteed over time as users move and services leave and join the network accordingly. A major challenge in pervasive environments is thus to maintain services functionalities despite the dynamics of the environment, which induces connectivity loss with service instances. In this paper, we analyse the requirements to make distributed composite services able to face connectivity loss, i.e., able to dynamically adapt their configuration according to the networking environment. We then discuss the adaptation of relevant techniques that originate in the fault tolerance domain to the specifics of 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...
متن کاملA 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...
متن کاملCAMAC: a context-aware mandatory access control model
Mandatory access control models have traditionally been employed as a robust security mechanism in multilevel security environments such as military domains. In traditional mandatory models, the security classes associated with entities are context-insensitive. However, context-sensitivity of security classes and flexibility of access control mechanisms may be required especially in pervasive c...
متن کاملTrust in Pervasive Computing
Pervasive environments are comprised of resource-constrained mobile devices “limited” in their connectivity to other devices or networks due to the inherent dynamic nature of the environment. Limited connectivity to the Internet precludes the use of conventional security mechanisms like Certifying Authorities and other forms of server-centric authentication. Under these circumstances peer-to-pe...
متن کاملContext reasoning using extended evidence theory in pervasive computing environments
Most existing context reasoning approaches implicitly assume that contexts are precise and complete. This assumption cannot be held in pervasive computing environments, where contexts are often imprecise and incomplete due to unreliable connectivity, user mobility and resource constraints. To this end, we propose an approach called CRET: Context Reasoning using extended Evidence Theory. CRET ap...
