Economic Workflow Scheduling Strategy in Mobile Grid*

A wired Grid recognizes resources connected with a fixed network as shared resources. But the present computing environment is evolving to mobile computing environment that involves mobile devices and wireless network. Therefore, the next generation Grids should offer an environment that uses a mobile device as a Grid resource not recognized in wired Grids. It is necessary to develop a system model and a scheduling algorithm for economic scheduling paradigm and load-balancing, which consider both wired and wireless environment. In this paper, we propose a service based architecture that integrates wireless resources with wired resources using proxy-based method to be a resource consumer and a resource producer and suggest an adaptive scheduling strategy considering economy in Mobile Grid. Experimental results show that the performance of our proposed scheduling strategy is scalable in wired and wireless environments.
