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. This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).

协作网络通过有效地汇集被窃听的信息来利用无线信道的广播特性，而这些信息传统上被视为有害干扰。虽然在物理(PHY)层有一套成熟的工具可实现合作收益，但如何使用这些工具来显著提高网络容量仍不清楚。本项目的目标是设计和实施用于协作网络的跨层机制。通过将物理层协作与媒体访问控制(MAC)和应用层相结合，该项目将提供更高的网络容量和改善的多媒体质量。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结构：(I)协作数据传输，重点是在移动性和对同步和网络拓扑的松散要求下，结合多个中继的稳健协作MAC-PHY。(Ii)协作视频传输，它利用协作和分层压缩之间的协同作用来提供不平等的差错保护以及多播中的差异化质量。除了对新无线技术的理论和实践的潜在影响外，该项目还将在无线通信的各个方面培训本科生和研究生。纽约大学-保利与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)提供资金的。
