The advancement of technologies in the area of Ubiquitous Computing has resulted in a widespread use of services in order to improve the quality of human life. These services should be permeable to end-users so that they can compose and configure them in order to personalize them and have an experience of having proper control over them. On the other hand, adaptation during service usage is essential...
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...
Ambient-intelligence (AmI) systems raise a series of new challenges in software and system development: Mobility, adaptability and heterogeneity are new concerns that have to be addressed. Many of these concerns are common and therefore should be addressed by a common AmI infrastructure instead of each individual application. This position paper proposes a bottom-up approach for the development of...
While the advances in networking technologies actually enable mobility and ubiquity of access to computing resources located at different administrative domains, the progress in multimedia technologies has created large amounts of digital content that can be purchased and distributed on the Internet. Within this setting, the problem of the copyright protection of digital content has become a well-known...
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...
Emerging healthcare applications can benefit enormously from recent advances in pervasive technology and computing. This paper introduces the CLARITY Modular Ambient Health and Wellness Measurement Platform:, which is a heterogeneous and robust pervasive healthcare solution currently under development at the CLARITY Center for Sensor Web Technologies. This intelligent and context-aware platform comprises...
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...
Context-awareness is a vital requirement in building valuable and capable adaptive systems. Context-aware ubiquitous computing focuses on the use of context of users, devices, environment, etc in order to offer services essential for a particular person, space and time. This paper provides a survey of context-aware middleware architectures. An overview of each middleware is provided, along with the...
We are developing a new enhanced cloud-based computing architecture, called the Proximal Workspace architecture to allow access and interaction between lightweight devices, and applications that represent a new generation of computation-and-data-intensive programs. We are developing a new system architecture based on supporting workspaces which provide nearby computing power to the users devices and...
This paper describes the design and implementation of a pervasive computing framework, named Physicalnet. Essentially, Physicalnet is a generic paradigm for managing and programming world-wide distributed heterogeneous sensor and actuator resources in a multi-user and multi-network environment. Using a four-tier light-weight service oriented architecture, Physicalnet enables global uniform access...
We are developing a new enhanced cloud-based computing architecture, called the Proximal Workspace architecture to allow access and interaction between lightweight devices, e.g., video glasses, earphones, wrist displays, body sensors, etc., and applications that represent a new generation of computationand-data-intensive programs in areas such as augmented reality. While lightweight devices offer...
This article describes middleware by adopting a horizontal and a vertical layer views. Middleware are enabling technologies for application development and execution in ubiquitous environments. In the horizontal view, we find most types of middleware developed so far, such as MOM, ORB, databases middleware and more recently SOA. Two new concepts emerged in this category, the ``middleware of sensors"...
Based on an extensive examining of different industrial and research resources we have recognized that SOA is one of the most progressive IT concepts in the enterprise management. Besides, the rise of social networking in the enterprise, the adoption of Enterprise 2.0, and the use of mobile applications in business are influencing the enterprise SOA development. Thus, in this paper, we focus onto...
With the increasing demands for adaptive middleware of dynamic systems in ubiquitous computing environments, the need for dynamic software architecture and programming infrastructure to achieve dynamic adaptation is widely recognized. The paper firstly presents a semantic and adaptive middleware architecture called ScudWare that supports for ubiquitous computing environments. Specially, a Scud-ADL...
A smart space, i.e. a physical environment such as a laboratory or a home that can offer automatic services mainly relies on sensing devices to acquire contextual information, and on actuation devices to carry out context-aware responses. To deal with the great heterogeneity of these sensing and actuation devices with various hardware and software, this study is focused on the development of a general...
Ambient and pervasive networks is a new networking concept that targets forthcoming dynamic communication environments; characterized by presence of a multitude of different wireless devices, radio access technologies and network operators that can form instant inter-network agreements with each other. However, one challenge is the efficient utilization and management of the multi-radio resources...
Monitoring of the sub-sea environment requires advanced sensor networks with both stationary and mobile nodes on the surface and underwater, each node playing a different role. The combination of mobile and stationary nodes, the loss of nodes due to harsh conditions, the difficult conditions for wireless sub-sea communication and the need for nodes to collaborate are all factors that require new approaches...
Current information service systems are built to serve all users, independent of the special needs of any individual user in different situations. Personalized information service aims at improving the retrieval process by taking into account the particular interests of individual users. However, not all user preferences are relevant in all situations, and they should be understood in context with...
