A Service Oriented Architectural Model for Realizing Pervasive Grids

Technological advances in wireless networks and mobile devices are driving towards a new concept of grid computing, in which mobile users play an active role. For this reason, classical wired grid infrastructures are being extended in order to provide facilities which enable mobile users to exploit services available in the environment. Since grid computing borrows such facilities from pervasive computing, the new computing paradigm is named pervasive grid computing. In this paper, we identify a number of characteristics, like contextawareness and handling of mobile sessions, that all pervasive grid environments should provide. Accordingly, we define an architectural model based on a set of services. A running implementation of such an architecture and an application scenario are presented as well.
