NeTS: Medium: Collaborative Research: Unlocking Capacity for Wireless Access Networks through Robust Cooperative Cross-Layer Design

协作网络利用无线信道的广播特性，有效地汇集了传统上被视为有害干扰的窃听信息。虽然在物理层（PHY）有一套成熟的工具来获得协作收益，但如何使用这些工具来提供显著的网络容量收益仍然不清楚。该项目的目标是设计和实现协作网络的跨层机制。通过将物理层与介质访问控制（MAC）和应用层的协作集成在一起，该项目将提供更高的网络容量和改进的多媒体质量。该项目有两个相互关联的组成部分，研究下一代协作网络的基本架构：(i)协作数据传输，侧重于在移动性和对同步和网络拓扑的松散要求下结合多个中继的强大协作MAC-PHY。（ii）协作视频传输，利用协作和分层压缩之间的协同作用，提供不平等的错误保护，以及组播中的差分质量。除了对无线新技术的理论和实践产生潜在影响外，该项目还将培养无线通信各方面的本科生和研究生。纽约理工大学与WICAT成员公司的密切关系将促进对行业的影响。该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。

Cooperative networking exploits the broadcast nature of the wireless channel by effectively pooling the overheard information, which is traditionally treated as harmful interference. While there is a mature suite of tools at the physical (PHY) layer to harvest cooperative gains, it is still unclear how these tools can be employed to deliver significant network capacity gains. The goal of this project is to design and implement cross-layer mechanisms for cooperative networking. By integrating PHY layer cooperation with Medium Access Control (MAC) and application layers, the project will provide higher network capacity and improved multimedia quality. The project has two interrelated components investigating basic architectures for next generation cooperative networks: (i) Cooperative data transmission, which focuses on a robust cooperative MAC-PHY incorporating multiple relays under mobility and loose requirements on synchronization and network topology. (ii) Cooperative video transmission, which exploits the synergy between cooperation and layered compression in providing unequal error protection, as well as differential quality in multicast. Apart from potential impacts on the theory and practice of new wireless technologies, this project will train undergraduate and graduate students in all aspects of wireless communications. The impact on industry will be facilitated by the close relationship of NYU-Poly with WICAT member companies.
