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.

网络资源分配涉及有效管理可用的稀缺资源，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，网络信息理论开发了概念工具来建立新的机制来充分利用无线网络的能力。目前，无线网络的信息理论能力与现有资源分配方案所实现的性能之间存在显着差距。该项目旨在弥合这两个不同的观点，以缩小这一性能差距。为此，它在多用户通道的底层基础设施上开发实用的网络算法以及适当的信息理论机制。为实现这一任务，本课题主要围绕以下几个方向进行研究：（1）网络设计，涉及多用户信道的优化构建和动态更新； (2)网络控制，基于物理层和网络层的联合优化并开发必要的随机优化工具； (3)设计具有接近最优性能的低复杂度多用户信道调度器； (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，这将使我们能够设计和实现更快、更可靠、更鲁棒的算法。在各种条件下运行的无线网络。研究的传播将通过提交成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举办讲座和研讨会来实现。
