Integrating physical and information space into applications increases application's complexity and development difficulty. In Ubiquitous environment, context collection, aggregation and notification raise complex scientific problems and new challenges. In this paper we address these challenges by proposing a conceptual context-oriented middleware architecture. We first discuss the reason to use context...
Cars have become an increasingly important and exciting test bed for ubiquitous computing. However, smart car space is still little addressed in the literature to enable high adaptation in a mobile and resource-limited space. This paper focuses on building a context-aware software infrastructure for smart car space in middleware framework. To support context-awareness, we embed capabilities of context...
Currently, modeling and simulation systems have not gotten rid of “computer-centric” and “desktop computing” pattern. The new pattern of simulation of combing physical space with cyberspace can be realized by bringing pervasive technologies into simulation systems. Aiming at the characteristic and requirement of pervasive simulation, the pervasive simulation architecture based on Multi-Agent system...
Ubiquitous environments provide families of context-aware applications that are capable of exploiting the user mobility as well as the device variability. Typically, these applications retrieve context information from local and remote providers and react accordingly to the detected variations. However, this must be done by considering the heterogeneity of devices and protocols found in ubiquitous...
This paper describes the Context Awareness Framework developed for the HYDRA Middleware Project. The HYDRA project aims to develop middleware to support intelligent networked embedded system based on a service-oriented architecture, deployable on both new and existing networks of distributed wireless and wired devices. A well developed Context Awareness Framework (CAF) is crucial for the success of...
In the pervasive computing paradigm, there is a strong demand towards user-centric services based on the context and service management. For implementing the user-centric services recent researches on the service-oriented system is focused on the context recognition, analysis and reasoning. Furthermore, the service-oriented systems also need to manage the structural and hierarchical context model...
Pervasive applications, like smart living, geriatrics care, agricultural development, etc, are rapidly developed recently. Situation-awareness and workflow-centric are important characteristics of the applications. Service-oriented architecture which provides flexibility in integrating heterogeneous devices and communication networks might improve the execution of pervasive applications. To integrate...

In this paper we present an hybrid architecture for a computer supported collaborative work in pervasive computing environment simulator. This architecture supports pure simulation mode where all agents are simulated, real deployment where it seamlessly integrates pervasive computing to the computer supported collaborative work and finally an hybrid mode where real devices can interact with simulated...
Automotive software has increasingly become context-aware and adaptive to deal with dynamically changing environments. This paper presents our novel service-based approach to support the structural and behavioral adaptation of automotive telematics. We adopt services to (1) provide physical context facts and (2) facilitate context-aware interactions between entities of automotive telematics systems...
The Internet is expanding to reach the real world, integrating the physical world into the digital world in what is called the Real World Internet (RWI). Sensor and actuator networks deployed all over the Internet will play the role of collecting sensor data and context information from the physical world and integrating it into the future RWI. In this paper we present the SENSEI architecture approach...
Incorporating service composition and pervasive computing into managing user's complex everyday activities envisions the paradigm of pervasive service composition for everyday life. Context-aware pervasive service composition (CAPSC) enables a pervasive system to provide a user with service compositions that are relevant to the user's context. Moreover, CAPSC enables composition applications that...
Data as a Service (DaaS) emerges as a new trend for exchanging data between independent data owners and data users so that data can be acquired on demand through standard protocols across heterogeneous platforms. It is usually a user-interactive and iterative process to compose the services into various data-driven business scenarios of data acquisition, analysis, and other processing activities....
The availability of both static and dynamic context information has steadily been increasing in recent years. Accordingly, manifold use cases for this data, especially for consumer services, have been suggested. In this paper, we present a concept for how to use context information for intelligent radio network access (IRNA) purposes. Therefore, a context management architecture (CMA) is proposed...
Supporting dynamic attributes is critical in high quality Web service discovery. Presently, the methods used for service discovery assume that the world is static and, therefore, do not support attributes that are dynamic in nature. It is important to note that a service is characterized by both static and dynamic attributes. High quality Web service discovery requires detailed service context models...
The evolution of the ubiquitous computing requires a lot of efforts as for the design and the development of information systems. Indeed, the data come on the one hand, from different sources of very heterogeneous and distant information, and on the other hand, the users are more and more nomads and use multiple devices to reach information. The variation of these features entails changes of execution...
Pervasive applications are featured by their transient interactions, explicit surrounding contexts and by the flow of activities. Towards transparently tackling these features yet rigorously modelling and validating such applications, this contribution capitalizes on SE advances: (1) explicit separation of concerns (e.g. interaction-centric functionalities and context-awareness); (2) flexible description...
In ubiquitous computing environments, certain entities (or actors) often need to interact with each other in achieving a joint goal in a dynamically changing context. To perform such interactions in a seamless manner, the actors need to be aware of not only their physical context (e.g. location) but also their changing relationships with respect to the particular task or goal. The latter interaction-oriented...
This paper presents a context management system for supporting context-aware applications in a smart home. In a ubiquitous computing environment context changes dynamically and the applications have to adapt their behaviors according to the context. Therefore a context-aware system in a ubiquitous computing environment has to manage their context information effectively and satisfy qualities of context...
Pervasive simulation technology integrates and applies the pervasive computing technology, grid technology, distributed interactive simulation technology and Web technology to provide a simulation supporting platform. The pervasive simulation architecture can be built to encapsulate different simulation resources as services so that they can be shared and reused in WAN. It can support the access of...
