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的设备的大量激增，移动的云计算（MCC）已经作为云计算的新范例和扩展而出现，用户可以利用该MCC访问过多的独特功能。不幸的是，由于移动的用户将大部分计算和存储卸载到云，并且通常由电池供电，因此到云的高性能连接往往成为瓶颈，阻碍了MCC的效率。因此，到云的连接的吞吐量和能效是MCC中两个关键且具有挑战性的设计问题，应仔细解决。在这个项目中，PI提出了一种新的多无线电多信道多跳蜂窝网络架构，以促进MCC，并通过关注以下三个主要研究重点来研究吞吐量和能量优化：（1）混合模式下云用户与基站（U2 B）之间通信的吞吐量优化，（2）协作云用户（U2 U）之间通信的路径容量优化，以及（3）U2 B/U2 U通信的能量优化。本课题的研究成果将推动MCC网络优化技术的发展，丰富MCC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，它可以为创造就业机会，提高生产力和经济增长提供巨大的机会。该项目的成果将通过出版物和讲座传播。拟议的研究还将与课程开发，少数民族学生的招聘，培训和指导，并推广到K-12学生相结合。

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.
