Semantic Web Meets Autonomic Ubicomp
نویسندگان
چکیده
The placement of autonomic systems’ management functionality into a ubiquitous computing environment is a difficult task due to the lack of systems’ resources and the need for ‘intelligence’ to ensure that the system is selfhealing/organising or configuring. For such systems to adapt to changes to their current environment they need to be able to (re) configure the workflow of their services. In this paper, we propose the ANS, an autonomic middleware for ubicomp devices. We briefly describe the architecture of ANS and its autonomic behaviour. The ANS follows a service centric design and therefore lends itself to semantic service description. This paper introduces the concept of services with ancillary behaviour and illustrates the use of OWL-S to semantically describe them. Commitment is discussed as an example of ancillary behaviour which can be used to achieve self-healing at service level. We illustrate our approach with examples from the homecare scenario of a cardiac patient.

Toward a Shared Model for Wide Area Interoperability of Ubiquitous Computing Environments
Despite many years of ubiquitous computing (ubicomp) middleware research, deployment of such systems has not been widespread. For such systems to become more widely adopted, we argue that a shared model for ubicomp environments, and a system to bridge such environments between network and administrative domains is needed. This paper presents work in progress toward deriving a shared environment...
متن کاملSpinning Multiple Social Networks for Semantic Web
Social networks are important for the Semantic Web. Several means can be used to obtain social networks: using social networking services, aggregating Friendof-a-Friend (FOAF) documents, mining text information on the Web or in e-mail messages, and observing face-to-face communication using sensors. Integrating multiple social networks is a key issue for further utilization of social networks i...
متن کاملWapee: A Fault-Tolerant Semantic Middleware in Ubiquitous Computing Environments
A middleware in ubiquitous computing environment (UbiComp) is required to support seamless on-demand services over diverse resource situations in order to meet various user requirements [11]. Since UbiComp applications need situation-aware middleware services in this environment. In this paper, we propose a semantic middleware architecture to detect errors, analyze causes of errors, and plan se...

Towards a multi-agent planning based architecture for semantic Web Service Composition
With the rising popularity of Web services due to their potential to enable interoperability between applications implemented on different platforms, new issues far more complex and crucial than interoperability have appeared. The present paper considers an important problem related to the further development of the semantic Web service technology – the automated dynamic composition of Web serv...
