Current generation grids are implemented using heterogeneous/homogeneous PCs. The conception of this paper is to do the same with mobile phones, providing ubiquitous computational power to the mobile device which off-loads the processing burden on it over to the cluster. Such architecture provides anytime-anywhere access to data and computational power. Combining Mobile computing and grid technologies could mean the ability to recreate the power of supercomputers with a mobile device, anywhere, anytime. The confluence of these two emerging trends leads to two scenarios - Treating the mobile as an interface to the grid, or using the mobile as a resource in the grid. This paper focuses on the former, given its low processing resources and data rate constraints. A proxy-based architecture is used wherein the proxy will be a personal computer which acts as the master of a centralized grid. It takes care of job-scheduling in the grid based on the availability of resources. A mobile phone submits the job to the proxy through an indigenous front-end that has been implemented using J2ME which is compatible with most mobiles.
