Efficient Computational Grid Middleware for Mobile Device

With the rapid advances of mobile computing and grid technology, it has increasingly the trend to offer a mobile computational grid environment. Mobile users usually use mobile agent to submit their computing requests to computational grids on the Internet. On the cases of multiple operations over single dataset, single operation over multiple dataset, or multiple operations over multiple datasets, mobile device maybe need to delivery multiple large datasets or multiple operations to computational grid for submitting request. That will incur redundant packet delivery and diminish the performance. In this paper, we propose a mobile computational grid environment for supporting multiple invocations on multiple dataset in a request in order to reduce the communication overhead greatly. Mobile users can submit their request involving multiple operations or multiple dataset in an open standard format, such as XML. Obviously, the environment also supports parallel invocation over computational grid.
