Recently, there has been increasing work in using policy in pervasive systems. Policy is a relatively new field and much work is still required to explore designs, concepts, and architecture for using policy in pervasive computing environments. In this paper, we briefly introduce the concepts and design of a policy based pervasive system, using Mobile(More)
In this position paper, we present an abstraction framework that supports seamless migration of application logic between programming languages. It promotes the longevity of business rules and permits retargeting of these functions into numerous physical object oriented programming languages. We further demonstrate the framework through its ability to(More)
Content Extraction Signatures (CES) enable selective disclosure of verifiable content, provide privacy for blinded content, and enable the signer to specify the content the document owner is allowed to extract or blind. Combined, these properties give what we call CES functionality. In this paper we describe our work in developing custom transform(More)
As Web service technology evolves, the idea of context-aware services gains more interest. An idea is that different sets of services will dynamically drop into the mobile users' devices depending on their contexts. To do this effectively requires location modelling and representation as well as spontaneity in downloading and executing the service interface(More)
Context sensitivity is particularly useful if we want to give mobile users an experience of responsive and attentive services depending on their current contexts. However, to support proactive context awareness in mobile environment requires the sufficient accuracy of location positioning system and spontaneously way of downloading and executing the context(More)
The mobile agent approach has become popular due to recent developments in the mobile code paradigm and enabling programming technologies. Many existing agentbased systems lack clear standards and rely upon their own approaches and solutions to challenging research problems. Additionally, this rapid evolution has been poorly supported with formal methods.(More)
With the increasing use of mobile workstations for a wide variety of tasks and associated information needs, and with many variations of available networks, access to data becomes a prime consideration. This paper discusses issues of workstation mobility and proposes a solution wherein the data structures are accessed in an encapsulated form through the(More)
