Adaptation as an Aspect in Pervasive Computing
نویسندگان
چکیده
Adaptation is one of the key characteristics of pervasive computing applications. However, implementing adaptation using conventional development techniques is challenging as adaptation requirements tend to affect multiple elements of a pervasive environment. In this paper, we present our experience with implementing adaptation using aspect-oriented programming (AOP). We argue that the use of AOP not only provides an improved modularisation of the adaptation concern but also makes it easier to adapt the pervasive application to both changes in data and reorganisation of the pervasive environment itself.

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...

Recent years have seen an increasing interest in research into and development of pervasive and ubiquitous computing environments. Such environments require a high degree of adaptability and are often inherently distributed in nature. Adaptation and distribution are properties with a crosscutting nature as the need for adaptation is determined by the context in which various elements of the env...

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...
