When the Grid becomes pervasive: A vision on Pervasive Grids,” presented at the

Grid computing has emerged as the dominant paradigm for wide-area distributed computing [3]. The goal of the original Grid concept is to combine resources spanning many organizations into virtual organizations that can more effectively solve important scientific, engineering, business and government problems. Over the last decade, significant resources and research efforts have been devoted towards making this vision a reality and have lead to the development and deployment of a number of Grid infrastructures targeting a variety of applications. However, recent technical advances in computing and communication technologies and associated cost dynamics are rapidly enabling a ubiquitous and pervasive world- one in which the everyday objects that surround us have embedded computing and communication capabilities and form a seamless Grid of information and interactions. As these technologies weave themselves into the fabrics of everyday life [6], they have the potential of fundamentally redefining the nature of applications and how they interact with and use information. This is rapidly leading to a new revolution in the original Grid concept and leading the way to a Pervasive Grid vision. The Pervasive Grid vision is motivated by the advances in Grid technologies and the proliferation of pervasive systems, leading to a seamless integration of sensors, light devices, together with classica
