In this project, the PIs will focus on the emerging Dynamic Spectrum Access (DSA) Wireless Mesh Networks (WMNs). Cross-layer design is strongly needed for such a network due to its two special features; dynamic spectrum availability and spectrum heterogeneity. Quite different from other well-studied wireless networks, such as mobile ad hoc networks and wireless sensor networks, the major concerns of WMNs are throughput, fairness, and QoS support, instead of mobility support and power efficiency.The PIs plan to conduct a comprehensive study on cross-layer optimization in DSA WMNs, and design protocols under the guidance of this cross-layer optimization. They will concentrate on the bottom four layers of the network stack and seek joint congestion control, routing, spectrum sharing, and power control solutions with the objective of maximizing throughput, achieving certain fairness, and providing QoS support. Furthermore, the research will be conducted under various network models including different interference models, different traffic models, and different fairness models.The INTELLECTUAL MERIT of the project includes (1) a unified mathematical model which precisely characterizes all important features and the formal formulations of the cross-layer optimization problems under different network models, (2) centralized and distributed algorithms for solving the optimization problems, and (3) a spectrum-aware routing protocol.The BROADER IMPACT of the project includes (1) novel cross-layer schemes for emerging DSA WMNs, with impact on the advancement of information technology, (2) high quality publications and training of highly skilled students, and (3) possible impact on the standardization in IETF and IEEE for DSA wireless networks in the future.

在此项目中，PI将重点关注新兴的动态频谱访问（DSA）无线网络网络（WMN）。由于其两个特殊功能，这种网络非常需要跨层设计。动态频谱可用性和频谱异质性。 WMN的主要关注点是与其他实践良好的无线网络（例如移动临时网络和无线传感器网络）的不同之处，而不是移动性支持和功率效率。他们将专注于网络堆栈的底层四层，并寻求联合的拥塞控制，路由，频谱共享和电力控制解决方案，目的是最大化吞吐量，实现某些公平性并提供QoS支持。此外，该研究将在各种网络模型下进行，包括不同的干扰模型，不同的交通模型和不同的公平模型。项目的智力优点包括（1）统一的数学模型，该模型精确地表征了所有重要特征以及在不同网络下的跨层优化问题的正式表征以及在不同的网络模型下的正式表述，（2）集中和分布的范围，（2）跨越了范围的范围，以置换优化的问题，以及（3）途径，（3）AUFERS和3（3）AUFERS，（3）（3），以及（3），以及（3）途径（3），（3）（3），以及（3）途径，（3）；该项目包括（1）针对新兴DSA WMN的新型跨层计划，对信息技术的发展影响，（2）（2）高质量的出版物和高技能学生的培训，以及（3）将来对IETF和IEEE的标准化可能影响DSA无线网络的标准化。
