Real-World Challenges of Pervasive Computing

Proceedings Eighth Workshop on Hot Topics in Operating Systems

Pervasive computing, with its focus on users and their tasks rather than on computing devices and technology, provides an attractive vision for the future of computing. But, while hardware and networking infrastructure to realize this vision are becoming a reality, precious few applications run in this infrastructure. We believe that this lack of applications stems largely from the fact that it is currently too hard to design, build, and deploy applications in the pervasive computing space. In this paper, we argue that existing approaches to distributed computing are flawed along three axes when applied to pervasive computing; we sketch out alternatives that are better suited for this space. First, application data and functionality need to be kept separate, so that they can evolve gracefully in a global computing infrastructure. Second, applications need to be able to acquire any resource they need at any time, so that they can continuously provide their services in a highly dynamic environment. Third, pervasive computing requires a common system platform, allowing applications to be run across the range of devices and to be automatically distributed and installed.

This paper describes the recent topic pervasive computing which focuses on introduction, its architecture, applications, issues and challenges of pervasive computing. The pervasive computing is the latest computing technology. Pervasive computing is an advanced computing paradigm which makes computing available everywhere and anywhere .The pervasive architecture rates how the end-user interacts with the pervasive network using the middle were support. Applications in such technology bring together devices connected through a heterogeneous network, services and resources are also brought together to enable information integration that is context-aware. Finally it explains about the future possibilities of pervasive computing through real time applications. The work presented in this paper deals with such problems from a design perspective and derives a new research for pervasive mobile assistance in the above-mentioned scenarios.

Abstract: Computing world is an incredibly growing area having pervasive computing as an emerging computing environment. The aim of pervasive computing is to create such an environment that is familiar to the user and this is done by embedding multiple electronic ...

Many predict that the computing environment of the future will be characterized by the presence of numerous invisible sensors and computing elements, autonomously interacting with each other to dynamically construct and provide services to users that enter and leave the environment. The software challenges to turn such pervasive or ubiquitous computing environments into reality are enormous, to say nothing of the hardware and social challenges. These challenges question many of the assumptions we are used to making and many of the solutions we are used to applying in our current software systems. In this talk, I will review some of the work of my group in the areas of software components, security and access control, and device independent Web access and then analyze where our solutions are lacking and must be adapted fo r pervasive computing.

Pervasive computing is a new dimension of personal computing that integrates mobile communication, ubiquitous embedded computer system, consumer electronics and power of Internet. It is a rapidly developing area of Information and Communications Technology (ICT). The term refers to the increasing integration of ICT into people's lives and e nvironments, made possible by the growing availability of microprocessors with inbuilt communications facilities. Pervasive computing has many potential applications, from health and home care to environmental monitoring and intelligent transport systems.

As mobile and embedded computing devices become more pervasive, it is becoming obvious that the nature of interactions between users and computers must evolve. Applications need to become increasingly autonomous and invisible, by placing greater reliance on knowledge of context and reducing interactions with users. Moreover, applications must cope with highly dynamic environments in which resources, such as network connectivity and software services, frequently vary over time. This paper presents our vision of pervasive computing and enumerates the software engineering challenges involved in realizing this vision. It also evaluates the current state of research and presents an agenda for future investigations in pervasive computing.

This paper challenges the mobile computing community by questioning the roles of devices, applications, and a user's environment. A vision of pervasive computing is described, along with attributes of a new application model that supports this vision to reality. Pervasive computing is more art than science. It will remain this way as long as people continue to view mobile computing devices as mini-desktops, applications as pro-grams that run on these devices, and the environment as a virtual space that a user enters to perform a task and leaves when the task is finished. This paper challenges the mobile computing community to adopt a new view of devices and its applications.

As an emerging field, pervasive computing has not had the opportunity to develop a conceptual model similar to the OSI Reference Model that is used to describe computer networks. Such a model would be useful in properly classifying design issues and providing needed context. Inspired by the layers of abstraction provided by the OSI Reference Model, we present our Layered Pervasive Computing (LPC) model to facilitate discussion and analysis of pervasive computing systems by providing a much needed conceptual framework. A key feature of our model is its representation of the human user at each layer of abstraction of the model. We then use our model to analyze a research prototype created as part of our Aroma pervasive computing project. This analysis is illustrative because it quickly reveals issues that must be addressed to realize our research prototype as a commercial product
