Abstract:
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 these techniques, we present an application model composed of a situation model, workflows, and required services for development of pervasive applications. A service-based framework supporting situation-awareness and workflow management is sketched to support execution of pervasive applications. This paper also presents the framework and its pervasive applications development. Finally, a case study is used for demonstration.Keywords:

The main focus of this research will be on pervasive computing. Pervasive computing, (also called ubiquitous computing) is the growing trend towards embedding microprocessors in everyday objects so they can communicate information. Pervasive computing devices are completely connected and constantly available. Throughout this research pervasive computing will be defined, examples will be provided, and we will discuss it’s relevancy as time goes forward. Towards the end of our research we will provide an idea that could ease the human experience with respect to pervasive computing.

Pervasive computing environment is viewed as an incorporate space in which it comprises mobile users,system services,system resource,and sensors embedded in the physical environment.Users can visit resources and obtain services anytime anywhere.However,the ubiquitous and mobile environment presents a new challenge.It is unsuitable for pervasive computing environment that entities are not foreknow for each other to use identity-based access control that suitable for static and closed environment.In this paper,a dynamic access control model for pervasive computing is presented,which can be used to secure pervasive computing applications.

1. INTRODUCTION Pervasive Computing integrates computation in the environment rather than computers which are distinct objects. Other terms for pervasive computing ubiquitous computing, calm technology, things that think and everyware. In other pervasive computing means computers everywhere, making them available the physical environment while making them effectively invisible to the user. having a desktop or a laptop machine, the technology pervasive computing embedded in the environment. Ubiquitous technology is often wireless, networked making its users more connected to the world around them and the it. Through pervasive computing, users use today's digital tools like laptops, phones, PDAs, smartphones to communicate and exchange information in different and conceive and use the geographical and temporal spaces differently. In being an aspect of information dissemination, pervasive or ubiquitous computing global and local, social and personal, invisible and visible at the same time.

Pervasive computing environments based on the ubiquitous communications paradigm have attracted significant research interest and have found increased applicability in commercial settings, attributed to the fact that they provide seamless, customized and unobtrusive services to their users. The majority of solutions proposed in the related literature to enable pervasive computing involves specific platforms and rigid architectures that are tightly bound with their target applications and services. This approach suffers from having to introduce new context-aware applications, thus limiting deployment in existing configurations. Nevertheless, the notion of pervasive computing calls for solutions to be tailored to user needs and not conversely. In this paper we introduce a framework that enables systems to become pervasive in a transparent manner, handling context monitoring and ubiquitous communications issues behind the scenes without affecting existing applications. Pervasive behavior is guaranteed by adapting systems based on monitored context information and guiding their re-configuration. We present the architecture of our proposed framework and discuss application scenarios, while considering evaluation aspects.

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 devices in user environment without making the technology and the computing devices visible to the user. After revolutionizing the business world pervasive computing is being making changes in the homes. This paper introduces the emergence of pervasive computing in the homes. Based on interviews conducted at home we explored the multiple user prospects about the pervasive computing environment at homes. The paper ends up with the discussions on the challenges and the future devices of pervasive computing at homes.

Mark Weiser described a hypothetical world in which humans and computers were seamlessly united in a seminal article a decade ago; he called this vision ubiquitous computing (which now is also called pervasive computing). After that, technology has advanced along many dimensions, especially in hardware progress and wireless communication technologies. A number of leading technological organisations are exploring pervasive computing. But it is far from Weiser's vision become reality. Pervasive computing will be the future. Pervasive computing will be a fertile source of challenging research problems in computer systems for many years to come. But until today, there is less attention to the system evolution in pervasive computing environment. This paper discusses the current development of pervasive computing and technical challenges in deploying pervasive computing systems. First, a model for evolution of pervasive Information technology infrastructure of pervasive information is presented which shows how the existing technologies solutions available can be used to develop a pervasive information infrastructure. Then a generic architecture of pervasive computing system is given. Based these, an evolutionary system design approach is suggested.
