Abstract
With the rapidly development of mobile cloud computing, in order to provide a better experience for mobile users, the computing and storage functions of mobile terminals are migrated to the cloud. In the application research of virtual machine migration, the transmission rate of wireless channel will changed with the changes of network condition. This paper focuses on the pre-copy transmission algorithm in the process of virtual machine migration in mobile cloud computing. A pre-copy transmission algorithm based on optimal stopping theory (PTAOST) was proposed, the algorithm constructs an optimal stopping problem based on an optimal transmission rate in the process of virtual machine migration. And we solve the model by using the optimal stopping theory, and get an optimal transfer rate. So the total amount of data and migration time is reduced during the process of virtual machine migration. In simulations, the PTAOST is compared with the transmission algorithms offered by some literatures, and we obtained some comparable results about the total migration data and total migration time to different transmission algorithms. The simulative results show that the proposed algorithm has less the total amount of migration data and total time of migration and improves the performance of migration.
