移动云计算环境下终端任务卸载研究

The research of task offloading in mobile cloud computing

随着移动计算技术的发展,移动终端在计算、存储和网络等方面的资源受限问题突出,现有移动终端往往不能够很好地支持复杂高端应用的运行。目前克服资源受限问题的解决方法之一就是将终端计算任务卸载迁移到云上,通过将计算任务转移到云端,能够提高任务处理效率并显著降低能源消耗和设备时延等带来的一系列问题,由此需要对移动云计算任务卸载问题进入深入的研究。本文主要内容是介绍任务卸载迁移过程中的卸载策略,以及任务卸载的系统框架及相关技术。通过对任务卸载进行系统分析之后,探讨了卸载技术未来的发展方向与面临的挑战。

With the development of mobile technology,the problem of limited resources for mobile terminals in computing,storage and network is outstanding,modern mobile terminals are often not able to support high-end applications run well.Today,one of the solutions to overcome the problem of limited resources is discharging the task to the cloud computing,through shifting to the cloud computing,we can improve the processing efficiency and significantly reduce energy consumption and the delay of equipment,etc.So there is a need to carry out in-depth research on mobile cloud computing task unloading problem.The main content of this article is to introduce the task offloading strategy in the process of migration,unloading system framework and task.Through analysising the task after offloading system,we will discusses the development direction of the future and the challenge for unloading technology.
