CAREER: Multi-Radio Multi-Channel Multi-Hop Cellular Networks: Throughput and Energy Consumption Optimization

由于智能手机和平板电脑等移动设备的大量涌现，移动云计算(MCC)已经成为云计算的新范式和新延伸，用户可以通过移动云计算访问大量独特的功能。遗憾的是，由于移动用户将大部分计算和存储卸载到云上，并且通常使用电池供电，因此高性能的云连接往往会成为瓶颈，阻碍MCC的效率。因此，连接到云的吞吐量和能效是MCC中两个关键且具有挑战性的设计问题，应该仔细解决。在本项目中，PI提出了一种新的多无线电多信道多跳蜂窝网络架构来促进MCC，并围绕以下三个主要研究方向对吞吐量和能量优化进行了研究：(1)混合模式下云用户与基站(U2B)通信的吞吐量优化；(2)云用户之间协作通信(U2U)的路径容量优化；(3)U2B/U2U通信的能量优化。本项目的研究成果将促进移动通信网络优化研究的发展，丰富网络设计的科学知识。因此，拟议的研究对MCC的成功至关重要，MCC可以为创造就业机会、提高生产率和经济增长提供巨大机会。该项目的成果将通过出版物和讲座进行传播。拟议的研究还将与课程开发、招募少数族裔学生、培训和指导以及向K-12学生进行外联相结合。

Due to the massive proliferation of mobile devices like smart phones and tablets, mobile cloud computing (MCC) has emerged as a new paradigm and extension of cloud computing, with which users can access a plethora of unique features. Unfortunately, since mobile users offload most computation and storage to the cloud and are usually battery-powered, high performance connections to the cloud tend to become the bottleneck, hindering the efficiency of MCC. Thus, throughput and energy efficiency for the connections to the cloud are two critical and challenging design issues in MCC, which should be addressed carefully. In this project, the PI proposes a novel Multi-radio Multi-channel Multi-hop Cellular Network architecture to facilitate MCC, and investigates throughput and energy optimization by focusing on the following three main research thrusts: (1) throughput optimization for communications between cloud users and base stations (U2B) in hybrid mode, (2) path capacity optimization for communications among cloud users (U2U) with cooperation, and (3) energy optimization for U2B/U2U communications. The results of this project will advance the state of the art in network optimization for MCC and enrich the scientific knowledge of network design. The proposed research is thus crucial to the success of MCC, which can provide great opportunities for job creation, greater productivity, and economic growth. The results of the project will be disseminated through publications and talks. The proposed research will also be integrated with curriculum development, minority student recruitment, training and mentoring, and outreach to K-12 students.
