Abstract | The emergence of pervasive and mobile computing has drawn research attention to integrated mobile Grid systems. These new hybrid Grids consist of a typical SOA backbone extended to include mobile and small scale devices such as personal digital assistants, smart-phones, multimedia devices, and intelligent sensors. In a fully integrated model, mobile devices are able to act both as consumers and providers to open up a completely new range of very interesting possibilities in exploiting their mobile nature, unique functionality, and context awareness. However, in resource-limited environments, traditional SOA frameworks cannot easily be deployed since they assume a plethora of available device resources, and have a number of complex dependencies, thus rendering them unsuitable for resource-constrained devices. Therefore, a smaller and simpler server-side container with reduced requirements and dependencies is needed. The contribution of this paper is two-fold: first, we have designed a J2ME-compliant socketbased server-side container, and second, we have demonstrated how an aggregator framework enables such mobile services to be accessed using standard-based Web services in a high-level manner. |
