CAREER: Design and Control of Wireless Networks on Network-Information-Theoretic Foundations

网络资源分配涉及有效地管理可用的剩余资源，其目的是为我们提供实用的算法来实现无线网络的高性能。另一方面，网络信息理论发展了概念工具，以建立新的机制，充分利用无线网络的能力。目前，无线网络的信息理论容量与现有资源分配方案的性能之间存在着巨大的差距，本项目旨在弥合这两个独立的观点，以缩小这一性能差距.为此，它开发了实用的网络算法在多用户通道的底层基础设施与适当的信息理论机制。为了完成这一任务，它沿着以下主要研究方向进行：（1）网络设计，包括多用户信道的优化构造和动态更新;（2）网络控制，基于物理层和网络层的联合优化以及必要的随机优化工具的开发;（3）具有接近最优性能的低复杂度多用户信道分配器的设计;（4）通过真实的链路级测量对所开发的算法进行性能评估，研究结果有可能使我们的性能提高一个数量级以上，这将使设计和实现更快，更可靠，更健壮的无线网络在各种条件下运行。研究的传播将通过提交结果在学术期刊上发表，在会议和研讨会上发表，以及在学术和工业环境中的讲座和研讨会来实现。

Network resource allocation deals with efficiently managing thescarce resources available with the objective of providing uswith practical algorithms to achieve high performance inwireless networks. On the other hand, network informationtheory develops conceptual tools to build new mechanisms toexploit the full capacity of wireless networks. Currently thereis a significant gap between the information theoreticcapacities of wireless networks and the performances achievedby existing resource allocation schemes.This project aims to bridge these two separate perspectives to closethis performance gap. To that end, it develops practical networkalgorithms over an underlying infrastructure of multiuser channelsalong with the appropriate information theoretic mechanisms. To achievethis task, it proceeds along the following main research thrusts: (1)network design, which involves the optimal construction and dynamicupdate of multiuser channels; (2) network control, based on jointoptimization of physical and the network layers and the development ofthe necessary stochastic optimization tools; (3) design oflow-complexity multiuser channel schedulers with a near-optimalperformance; (4) performance evaluation of the developed algorithmsthrough real link-level measurements.The outcome of the research has the potential to give us performancegains by more than an order of magnitude, which will enable the designand implementation of faster, more reliable, and more robust wirelessnetworks operating under a variety of conditions. Dissemination of theresearch will be achieved by submitting the results for publication inrefereed scholarly journals, presentation in conferences and symposia,and lectures and workshops in academic and industrial settings.
