The way in which the computing devices and applications are developed and used does not satisfy the needs of the users calling for and shots of the potential for pervasive computing. It is crucial that the provides have full visibility of their context i.e., the set of available and relevant resources depending on access control rules, client locations user preferences, privacy requirements, terminal characteristics and current state of hosting environments. The applications developed for pervasive computing are very hard, but they are necessary to build ubiquitous computing environment. Few researchers have indeed focused on some of these requirements but there is a practical difference between theory and its achievement. A new model is proposed for pervasive computing. A solution to the existing problems is proposed through this paper. Some of the ways to improve the performance environments through the use of middleware is also proposed in this research work.
