Mobile cloud computing (MCC) has been used to address the resource limitation of mobile devices by migrating expensive local computations to the cloud. However, transmitting data wirelessly from mobile devices to the cloud also consumes energy. Hence, the key problem of MCC is how to minimize the energy consumption while preserving the mobile application performance. Different from traditional solutions which focus on reducing the cost of wireless transmission solely from the application perspective, this project focuses on designing MCC schemes from a network-centric perspective, by investigating, formulating, and mitigating the impact of special characteristics of wireless networks on the energy efficiency of MCC. The proposed research could benefit end users with various mobile devices by extending their battery lifetime and improving their performance. The results from this research are likely to foster new research directions on supporting MCC from a network-centric perspective. The project will engage under-represented students in the proposed research, and the scholarly discovery of this project will be disseminated broadly to the community. This project aims to improve the performance of MCC by mitigating the impacts of two special characteristics of wireless networks: the long-tail problem at the wireless interface and the quality variations of the wireless link. More specifically, this project consists of three closely intertwined research thrusts: (i) reducing the amount of tail energy when transmitting the program states to the remote cloud, while ensuring that the performance requirements of mobile applications can be met; (ii) mitigating the impact of wireless link quality on both energy and performance, and minimizing the degradation of application performance when the wireless link quality is low; and (iii) exploiting the difference of wireless link quality among mobile users to further improve the energy efficiency of MCC via user cooperation. An experimental testbed will be developed to investigate the practical impact of wireless network characteristics on MCC and evaluate the proposed MCC schemes.

移动云计算（MCC）已通过将昂贵的本地计算迁移到云中来解决移动设备的资源限制。但是，将数据从移动设备无线传输到云也会消耗能量。因此，MCC的关键问题是如何在保留移动应用程序性能的同时最大程度地减少能耗。 与仅从应用程序角度降低无线传输成本的传统解决方案不同，该项目通过调查，制定和减轻无线网络特征对MCC能源效率的特殊特征的影响来从以网络为中心的角度设计MCC方案。 拟议的研究可以通过延长电池寿命并提高性能来使最终用户使用各种移动设备。 这项研究的结果很可能从以网络为中心的角度促进了有关支持MCC的新研究方向。 该项目将与人数不足的学生参与拟议的研究，该项目的学术发现将大量传播给社区。该项目旨在通过减轻无线网络的两个特殊特征的影响来提高MCC的性能：无线界面的长尾问题和无线链接的质量变化。 更具体地说，该项目由三个紧密相互交织的研究推力组成：（i）在将程序传输到远程云时减少尾巴能量的量，同时确保可以满足移动应用程序的性能要求； （ii）减轻无线链路质量对能源和性能的影响，并在无线链路质量较低时最大程度地减少应用程序性能的降解； （iii）利用移动用户之间无线链路质量的差异，以进一步通过用户合作提高MCC的能源效率。 将开发一个实验测试床，以研究无线网络特征对MCC的实际影响，并评估所提出的MCC方案。
