AN ARCHITECTURE FOR UBIQUITOUS APPLICATIONS

This paper proposes a framework intended to help developers to create ubiquitous applications. We argue that context is a key concept in ubiquitous computing and that, by nature, a ubiquitous application is distributed and needs to be easily deployable . Thus we propose an easy way to build applications made of numerous modules spread in the environment and interconnected. This network of modules forms a permanently running system. The control (installation, update, etc.) of such a module is obtained by a simple, possibly remote, command and without requiring to stop the whole system. We ourselves used this architecture to create a ubiquitous application, which we present here as an illustration.
