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.

在该项目中，pi将重点关注新兴的动态频谱接入（DSA）无线网状网络（WMNs）。由于这种网络有两个特殊的特点，因此迫切需要跨层设计；动态频谱可用性和频谱异质性。与其他得到充分研究的无线网络（如移动自组织网络和无线传感器网络）完全不同，WMNs的主要关注点是吞吐量、公平性和QoS支持，而不是移动性支持和功率效率。pi计划对DSA wmn的跨层优化进行全面研究，并在此跨层优化的指导下设计协议。他们将集中在网络堆栈的底层四层，寻求联合拥塞控制、路由、频谱共享和功率控制的解决方案，以最大限度地提高吞吐量，实现一定的公平性，并提供QoS支持。此外，研究将在不同的网络模型下进行，包括不同的干扰模型、不同的流量模型和不同的公平模型。该项目的智力优势包括：(1)一个统一的数学模型，精确地描述了不同网络模型下跨层优化问题的所有重要特征和形式公式；(2)解决优化问题的集中式和分布式算法；(3)频谱感知路由协议。该项目的更广泛影响包括：(1)新兴DSA WMNs的新颖跨层方案，对信息技术的进步产生影响；(2)高质量的出版物和高技能学生的培训；(3)对未来DSA无线网络的IETF和IEEE标准化可能产生影响。
