混合云用户计算工作量分解的博弈分析研究

Research of the game analysis of user computing workload decomposition in hybrid Cloud

在混合云计算环境下,如何合理地划分工作量是每个理性的用户所需要考虑的问题。构建了混合云计算工作量分解博弈模型,在用户通常考虑响应时间的情况下把花费也纳入考虑,即将以响应时间和花费为变量的函数作为效用函数,通过求解纳什均衡的方法分析用户的策略行为,从而决定用户的最优策略。通过仿真给出了不同响应时间和花费比率对用户均衡策略的影响并做出了比较分析。

In hybrid Cloud computing environment, how to reasonably divide the workload is essential for every rational user to be considered. The paper presents a hybrid Cloud computing workload factoring game theory model. Except that the response time performance has been usually taken into account in the related literature, the paper takes payment as utility function into account to game analysis and obtains user＇s optimal Nash equilibrium strategic. By simulating the equilibrium strategies, it shows the effect on the equilibrium strategies at different response time and payment ratio.
