> 中文摘要: 随着移动云计算方式正在逐步替代传统的Client-Server 方式,在移动云计算网络中,如何有效地分配云计算资源来尽量满足移动终端对云计算服务的需求,同时使得移动云计算网络的云计算资源利用率和系统收益最大,就成为当前云计算领域中一个重要的研究课题.首先提出了一种基于半马氏决策过程(SMDP)的移动云计算服务域动态云计算资源优化管理模型,通过该模型获得的云计算资源优化管理决策策略不仅能使移动云计算服务域的系统收益最大,同时也能提高云计算资源的利用率以及移动终端的用户满意度和服务质量(QoS),并能反映由于移动终端的服务请求到达移动云计算网络以及移动终端结束服务离开移动云计算网络而引起的云计算资源动态变化的真实情况.最后对提出的移动云计算服务域动态云计算资源优化管理模型的性能通过仿真进行了验证,实验仿真结果验证了理论分析的正确性.
Abstract:With mobile cloud computing system architecture gradually replacing the traditional Client-Server model, one of the most critical issues that needs to be addressed is the resource allocation deciding problem to resolve how a cloud could efficiently handle the cloud resources to satisfy the requirements of mobile device for cloud services. Simoultaneously, this is in effort to obtain the maximal utilization rate of cloud resources and system rewards of cloud. The study first proposes a novel cloud computing resource allocation model based on semi-Markov decision process (SMDP) to achieve the optimal resource allocation scheme in terms of maximal system reward, cloud resource utilization, and the QoS of mobile device while capturing the dynamics of resource request arrivals and departures. Finally, the performance of the proposed model is evaluated by the simulation results, which show that the obtained theoretic results are consistent with this simulation results.
