Emerging pervasive computing technologies transform the way we live and work by embedding computation in our surrounding environment. To avoid increasing complexity, and allow the user to concentrate on her tasks, applications in a pervasive computing environment must automatically adapt to their changing context, including the user state and the physical and computational environment in which ...

This paper presents a model for building context-based systems in pervasive computing environments from high level specifications. A pervasive computing environment is viewed as a collaboration space consisting of mobile users, system services, and sensors and resources embedded in the physical environment. The approach presented here is developed for building collaborative activities in which ...

This article reflects on the visions and motivations underlying Pervasive Computing advances made ending with considering future directions for field. It describes these in terms of four phases: 1) vision-inspired, 2) design engaging experiences, 3) innovation-based, 4) addressing societal challenges. is proposed that we will need to embrace a paradigm shift be far more challenging than previou...

Grid computing is a next level of infrastructure that provides dependable, consistent, pervasive, and inexpensive access to high-end computational capabilities with variety of shared resources. In this high end computing infrastructure job scheduling is a complex one due to grid infrastructures. This proposal gives a detail analysis of various scheduling algorithm based on different criteria su...

Pervasive Computing enlarged the traditional computing setting into the human layer of the earth. Different devices in pervasive environments are seamlessly integrated in various ways. Examples are wired and wireless networks, infrared connections, Bluetooth etc. Apart from these local ties, pervasive computing environments are mostly connected with the World Wide Web environment as the simple ...

Service composition allows distributed application, such as multimedia application, to be composed from atomic service units and to adapt dynamically to users’ requirements and environment conditions in pervasive computing system. It augments the adaptation action space for the application of pervasive computing. According to the multidimensional QoS (Quality of Service) requirement of pervasiv...

Pervasive computing environments are exciting new vision of the new computing era due to the recent wide advances in wireless communication and digital electronics. These environments are small smart worlds that have many advantages such as the continuous and distributed interaction with people using a variety of wireless devices (such as mobile phones and PDAs), which are ubiquitous but provid...

Pervasive computing requires the ability to detect user activity in order to provide situation-specific services. Case-based reasoning can be used for activity recognition by using sensor data obtained from the environment. Pervasive computing systems can grow to be very large, containing many users, sensors, objects and situations, thus raising the issue of scalability. This paper presents a c...
