中文摘要：

为了改善移动云计算中切换用户的服务质量,对基于移动代理的切换机制进行了研究,分析该机制下用户切换和接入控制问题,在切换业务占优的接入控制模型下,根据不同业务效益的差异建立效益函数,利用业务总效益最大原则提出了一种能保证切换用户可靠通信的接入控制算法.仿真结果表明,所提出的接入控制算法不仅能保证用户在切换时的通信可靠性,而且还能最大化系统的效益.

英文摘要：

To improve the quality of service of handoff users in mobile cloud computing, a handoff mechanism based on mobile agent is investigated. The problems of handoff and access control are analyzed. In access control of priority handoff call model, a cost function is described in terms of benefit differences between different kinds of calls. An access control algorithm based on maximum total benefit is proposed to ensure the reliability of communication for handoff users in mobile cloud computing. Simulation shows that the proposed access control algorithm not only ensures the reliability of communication when handoff occurs, but also maximizes benefits of the system.
