A global resource positioning system for ubiquitous clouds

We are witnessing the emergence of the ubiquitous resource-infinite computing paradigm. Significant benefits accrue, ranging from added convenience and services for users, to enhanced efficiency and reduced cost for organizations, to improved on-demand resource availability for under-connected areas, extreme environments and distress situations. To this end, we proposed PlanetCloud, a distributed platform that aims to facilitate ubiquitous cloud computing. Integral to PlanetCloud is a Global Resource Positioning System (GRPS), which is an opt-in dynamic spatiotemporal resource calendaring and scheduling system ubiquitously accessed via a portable application (termed iCloud). In this paper, we motivate and present the GRPS concept and its architecture. GRPS would enable the provisioning of, otherwise idle, fixed and mobile resources to effect ubiquitous computing clouds. It aims to aid the formation of mobile computing clouds by providing a dynamic real-time resource scheduling and tracking system that can be accessed through the iCloud. GPRS is designed to access and maintain dynamic data from spatiotemporal calendars, social networking and other sources to enhance resource discovery, forecasting and status tracking to provide access to the right-sized cloud resources anytime and anywhere. We provide an analytical model to compute the resource request-response time. Our results show that we can adapt the performance of a response according to node density and contention window size.
