摘要 针对低性能终端的复杂计算需求,设计了面向普适终端的云计算系统UbiCloud。通过对云中计算资源的描述、发现、访问、评价等问题进行研究,在前端普适终端与后端云之间构建虚拟计算环境,实现了一个异构终端的云计算服务发布及访问平台。在对服务质量的评价上结合AHP算法给出了一个有效的服务评价模型,在建立判断矩阵的过程中提出了两种一致性矩阵构建方法。最后对系统进行了性能测试,结果表明系统在应用响应时间等指标方面可以达到设计目的。 A cloud computing system,UbiCloud,was developed to enable the ubiquitous terminals access to powerful and reliable computing resources anywhere and anytime through building a virtual computing environment between the front-end ubiquitous terminals and the back-end servers(cloud).The experiment results show that the system perfor-mance is good enough to support most applications deployment on resource-poor terminals.
