Autonomous and dynamic Web service composition in wireless grids

In combination of Web service and wireless technology, grid computing is evolved into a de facto standard for shared-resource computations. Although numerous efforts have been made on the construction of grid systems, stateless Web service composition has not been addressed sufficiently in grid environment, which is usually service-conscious. This paper attempts to address this issue through a novel workflow model which not only builds tasks through Web services, also handles state control through the grid platform. Based on this model, a grid system can ultimately compose Web services and give user a better tool for supercomputing.
