摘　　要：针对移动云计算面临的一系列问题,如应用程序在网络上迁移问题、远程设备上执行时的网络延迟和非持续连接问题、跨云服务问题以及安全风险和隐私问题,提出了一种基于移动Agent范型的移动云计算架构,其中,在应用程序迁移中引入断点保存思想和事件重播机制,在移动Agent协同过程中使用优化过的合同网协议,利用移动Agent交换密钥进行身份认证。用有色嵌套Petri网描述了此架构的执行流程,并在此基础上设计了移动电子图书销售系统。This paper proposed a mobile cloud computing architecture based on mobile Agent paradigm concerning the problems faced by the mobile cloud computing, such as application migration on network, network latency and non-persistent connection issues caused by execution on the remote device, cross-cloud service problems, and security risks and privacy issues. In this architecture, break-point saving ideas and events replay mechanism were introduced in application migration issues, optimized contract net protocol was used in the synergy between the mobile Agents, and mobile Agent exchange keys for authentication. What＇s more, this paper described the workflow of this architecture using colored nested Petri nets, and designed a system of mobile e-book sales based on the architecture.
