摘要
论述了移动网格的基本概念和研究背景,综述了移动网格的体系结构、资源管理、任务调度、中间件、安全与容错等关键技术,尤其是资源的巨大数量和间歇连接特性为移动网格的实现带来最大挑战。详细地介绍了移动网格的国内外研究现状,对各种关键技术的研究成果进行了深入分析。最后对移动网格的发展进行了归纳,提出移动网格研究对象的扩展,即通过有线方式连接的普通节点如PC机也应容纳到移动网格中,并基于覆盖网的思想提出分布式体系结构。
The basic concept and background of mobile grid are introduced firstly, with a survey of the key techniques including architecture, resource management, job schedule, middleware and security.It is pointed out especially that the vast number and intermittent connection of resources bring great challenges to mobile grid.Then a detailed report on research status of mobile grid is given, the research results of the key techniques are also analyzed.In the end, the development of mobile grid is concluded, and it is proposed that mobile grid should be extended to ordinary nodes with wired connection such a PC.Overlay network-based distributed architecture are also discussed at last.
