移动云计算中一种虚拟机迁移的预拷贝传输策略研究.

Aiming at the performance optimization problem of the virtual machine migration process in mobile cloud computing, this paper proposed a pre-copy transmission strategy based on the optimal stopping theory. The strategy solved the optimal stopping model which looked for the optimal transmission rate with the optimal stopping theory,to obtain the optimal transmission rate. So that it resulted in the reduction of the total amount of migration data and the total time in the virtual machine migration process. In the simulation experiment .this paper compared the proposed transmission strategy with the referenced transmission strategies, and analyzed the performance of different transmission strategies. The experimental results show' that the proposed strategy get less total amount of migration data and total time,and can effectively improve the performance of the migration process.
