Pervasive Computing is a very challenging and complex domain that still lacks a comprehensive unified architecture. In this paper, we propose a reference architecture for pervasive computing that captures most, if not all, of the key challenges and provides a new architecture model that can be used in almost any business context. It provides conceptual views for the smart environment (SE), the smart object (SO), and the pervasive system (PS). We evaluated the model using a simulation prototype to predict its reliability at runtime.

The pervasive computing domain is a very challenging one and requires a robust architectural model to facilitate the production of its systems. In this paper, we explain a case study using a simulation prototype to validate our baseline architecture of a reference architecture for the pervasive computing domain. The simulation prototype was very useful in predicting the reliability and availability of the system using the baseline architecture during runtime.

This paper provides an overview of the Interactive Lab Environment (ILE) project and a report on its current status and future directions. ILE is the framework of a customized interactive lab environment for computing concepts and courseware that we developed for our department using Java.In essence ILE is a well-managed, networked set of resources that offers its users a collection of tools. The most significant of these tools are the flexible routes through an interactive learning environment combining the presentation of course information and notes, executable examples of learning materials, visual tools for presenting new concepts that are otherwise hard to visualize, and a quick means of communication within the academic unit. In addition to the ILE framework itself and a few course material demos, two interactive components were developed and implemented thus far, both of which are visual tools but with differing degrees of abstraction and disclosure.
