Abstract

Pervasive computing refers to embedding computers and communication in our environment. Pervasive computing provides an attractive vision for the future of computing. The idea behind the pervasive computing is to make the computing power disappear in the environment, but will always be there whenever needed or in other words it means availability and invisibility. These invisible computers won't have keyboards or screens, but will watch us, listen to us and interact with us.

Description of Pervasive Computing

Pervasive computing makes the computer operate in the messy and unstructured world of real people and real objects. Distributed devices in this environment must have the ability to dynamically discover and integrate other devices. The prime goal of this technology is to make human life more simple, safe and efficient by using the ambient intelligence of computers.

Pervasive computing environments involve the interaction, coordination, and cooperation of numerous, casually accessible, and often invisible computing devices. These devices will connect via wired and wireless links to one another as well as to the global networking infrastructure to provide more relevant information and integrated services. Existing approaches to building distributed applications, including client/server computing, are ill suited to meet this challenge. They are targeted at smaller and less dynamic computing environments and lack sufficient facilities to manage changes in the network configurations.Networked computing devices will proliferate in the user's landscape, being embedded in objects ranging from home appliances to clothing.

Applications will have greater awareness of context, and thus will be able to provide more intelligent services that reduce the burden on users to direct and interact with applications. Many applications will resemble agents that carry out tasks on behalf of users by exploiting the rich sets of services available within computing environments.
