目前，网格服务的访问仅限于资源丰富的设备，如桌面PC，但大多数移动的设备（与无线网络连接）不能直接访问网格网络，因为它们的资源限制。然而，将网格的潜力扩展到更广泛的受众有望增加灵活的使用和生产力。在本文中，我们提出了一个中间件体系结构，解决的问题，工作委托给网格服务，支持离线处理，安全通信，与异构移动的设备的交互，并按照设备规范格式化的结果。这是通过将资源密集型任务从移动终端外包给中间件来实现的。我们还证明，通过正式的建模，使用Petri网，这样的中间件的增加会导致最小的开销和获得的好处超过了这个开销。
Currently, access to Grid services is limited to resourceful devices such as desktop PCs but most mobile devices (with wireless network connections) cannot access the Grid network directly because of their resource limitations. Yet, extending the potential of the Grid to a wider audience promises increase in flexible usage and productivity. In this paper we present a middleware architecture that addresses the issues of job delegation to a Grid service, support for offline processing, secure communication, interaction with heterogeneous mobile devices and presentation of results formatted in accordance with the device specification. This is achieved by outsourcing the resource intensive tasks from the mobile device to the middleware. We also demonstrate through formal modeling using Petri nets that the addition of such a middleware causes minimum overhead and the benefits obtained outweigh this overhead.
