Service migration is important for the execution of distributed spatial tasks because the spatial data published in autonomous Grid node is often not permitted to be freely transferred in Spatial Information Grid. In this paper, we design and implement a scalable service migration framework. In our framework, all spatial services are composed of fine-grained meta-functional components and managed...
Spatial information grid is established in the environment of distributed grid. With the capability of offering required services, it can immediately customize specific services and resolve the problem in sharing and cooperation of distributed massive heterogeneous spatial data. Based on spatial information grid, aim of resource and information sharing mechanism is aggregating computing resource,...
