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. Theses 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.
