IPSS: uma plataforma de middleware para distribuição de informações em smart spaces

Abstract

The term ubiquitous computing took shape through Mark Weiser’s vision, who saw the possibility to integrate and make use of the computer invisible to the user, merging it with elements of everyday. However, this integration does not happen across the board, in every environment, but requires certain preparation of the space where the computing services will be provided to the users, by delimiting a physical area, called smart space. In this context, we specified a solution to the problem of distributing information intelligently to any application environment, based on the premise that each individual is, in a particular way, interested in specific informations, for instance, of the company where he works and places that he usually goes. It was built a model for the distribution of information focusing on the interests of each user, and from this model, we propose the architecture of the Information Provider for Smart Spaces (IPSS), a middleware platform that provides the necessary services to the distribution of information in ubiquitous environments. The IPSS was implemented using the Java programming language and the JMS’s communication middleware API. We also developed an application based on the IPSS, to be used in educational institutions, which allows the validation of the proposed work, serving as proof of concept.
