摘要
作为基于移动计算范型的迁移工作流研究的继续,建立一种无线迁移工作流环境中程序按需移动模型及其实现方法,以支持大型迁移工作流在资源受限移动设备上运行。首先给出了迁移工作流单元模型,它是支持无线环境下迁移工作流的基础,然后给出了迁移工作流按需移动系统架构,讨论了架构中各部分的功能,包括停靠站服务器和工作流管理机的实现机制,分析了通过反射对工作流单元的动态调整。实验表明,无线迁移工作流环境中程序按需移动模型合理,运行可靠,有效支持迁移工作流在无线环境中的应用。
In order to support large-scale migrating workflow program running on resonrce-limited mobile devices, a model called code-on-demand migration in wireless migrating workflow environment was introduced. Firstly the concept of the workflow unit was given, which was the basis for the cede-on-demand migration in wireless migrating workflow environment. Then some critical problems in the integrated architecture of the model were discussed, such as the structure of the dock server and the migrating workflow management server. At last, the model was implemented. The experiment indicates that the model is reasonable and its implementation is reliable. It effectively supports the application of the migrating workflow in the wireless environment.
