Middleware Services for Pervasive Grids

Grid computing and pervasive computing have rapidly emerged and affirmed respectively as the paradigm for high performance computing and the paradigm for user-friendly computing. These two worlds, however, can no longer be separated islands. As a matter of fact, pervasive and grid computing communities can both benefit from joining the two paradigms. This conjunction is already taking place. This paper presents a middleware for pervasive grid applications. It consists of a set of basic services that aim to enhance classic grid environments with mechanisms for: i) integrating mobile devices in a pervasive way; ii) providing context-awareness; and, iii) handling mobile users' sessions. Such services are OGSA compliant and have been deployed as grid services in order to be easily integrated in classic grid environments.
