Due to the high cost of replication, incurred mainly by consistency management, it may be infeasible to use uninformed object replication in collaborative applications in pervasive environments, since resources are constrained, nodes are heterogeneous, and application behaviour is highly dynamic. Consequently, this paper proposes an adaptive replication scheme that dynamically creates and releases...
To achieve timely response and treatment of life threatening injury or illness in mass gatherings, it is imperative to establish effective communication and coordination between emergency agencies and teams and provide them with ready access to real-time information. The service-oriented paradigm presents an elegant solution for developing a general and scalable architecture where emergency teams...
In this paper, we first discuss a necessity of a bridge engineer for a multi-lingual development team, who bridges gaps between different languages, cultures and social systems of a client and a vender to define a requirement specification of an application system. Next, we propose a concept of cloud-based support system for defining requirement specifications, consisting of two design assistant agents,...
Ad hoc collaboration across organizational boundaries is gaining importance. In a networked world, organizations interact across diverse system landscapes with partners and customers. Traditionally, facilitating the collaboration of dispersed participants in heterogeneous environments required the same software on all client systems. This entry barrier can be lowered by leveraging the ubiquitous web...
Future ubiquitous environments will be emerged over many of the computers that are dynamically networked. The personalized data collected by ubiquitous environment provide important information for ubiquitous applications. This type of application will form a peer to peer system over the Internet to offer common services. Providing architecture for large-scale personalized peer to peer information...
In ubiquitous home environment, it is essential that every personal devices at home and out-home can collaborate with others to provide users with the home services and personal contents anywhere and anytime. To achieve this, it is recommended the virtual overlay network where every device can collaborate with others in peer-to-peer manner to share contents, send messages, and control services remotely...
Our goal is to enhance on-site personalized access and recommendations for cultural heritage. We have designed and implemented the SMARTMUSEUM platform using adaptive and privacy preserving user profiling. The described recommendation system relies on combining a semantics/ontologies based approach with a data mining/statistics based approach. The paper presents the architecture and main methods of...
The rapid increase of mobile device usage across all organisational and social levels has sparked the development of pervasive solutions for the improvement of many daily processes. Recent advances in ubiquitous computing offer new opportunities, with the promise of providing a better modeling of the mobility, collaboration and context-awareness of the different actors involved. With increasing communication...
This paper presents a novel service discovery framework for ubiquitous computing called hierarchical ubiquitous computing service discovery framework (HUCSDF). HUCSDF offers a more flexible and scalable architecture which can combine the local services with remote services. Based on the novel architecture, HUCSDF possesses some useful characteristics such as supporting migration of user's personal...
Pervasive computing has created both new business opportunities and new challenges for the modern enterprises. An innovated business application integration pattern for collaborated enterprises with the traits of the variability and equality was presented, in which the key challenge is that there is not the need of a headquarters to govern the whole business across the enterprises with the common...
We propose the implementation of a new learning environment that can utilize the computer for things as basic as taking lecture notes in a conventional lecture. Though active learning is visible to the user, as computers have become ubiquitous, they will support the teacher during a lecture and the student in the class. We aim to nurture motivation for learning, study skills, cooperativeness, and...
