提案#：CNS 07-08989 PI(S)：Erkip，Elza Bertoni，Henry L.；Panwar，Shivenra S.；Wang，姚研究所：纽约布鲁克林理工大学，NY 11201-3840标题：IAD：合作网络测试床额REC：30万美元建议：该项目，为合作网络建设两个互补的测试床，针对衰落和多径失真，以及多用户在有限带宽上操作所造成的干扰，通常受到无线通信系统的影响。分别，每个试验床将。使用开源驱动程序向后兼容当前基于IEEE 802.11标准的WiFi技术。该方法使用标准的非协作物理层，因为它不可能访问商业产品中的物理层。基于软件定义的无线电，允许在协作物理层、协作媒体访问控制(MAC)层以及跨层设计中实现最大的灵活性。协作网络，其中网络中的两个或更多活动用户共享他们的资源以共同传输他们的消息，提供抗衰落、高吞吐量/低延迟和减少干扰/低发射功率。莱斯大学的WARP平台、罗格斯大学的轨道试验台和达特茅斯大学的Crawda数据库部分利用了这一基础设施，提供了一个开放访问平台，将用于构建试验性的可部署和可扩展的协作无线网络，使当前的技术能够超越当前的理论和模拟研究。试验台验证了协作网络的可行性，使新算法能够在平台上进行测试，并在更现实的假设基础上产生新的理论。布罗德影响：这是实施完全协作网络的第一次努力，预计将加速该领域的商业发展，并影响当前的无线标准。它有助于与工业界建立更紧密的关系。此外，基础设施还有助于培训学生和服务于新课程。

Proposal #: CNS 07-08989 PI(s): Erkip, Elza Bertoni, Henry L.; Panwar, Shivendra S.; Wang, YaoInstitution: Polytechnic University of New York Brooklyn, NY 11201-3840Title: IAD: Cooperative Networking Testbed Amount Rec: $ 300,000Project Proposed:This project, building two complementary testbeds for cooperative networking, responds to the fading and multipath distortion, as well as interference caused by multiple users operating over a limited bandwidth, often suffered by wireless communication systems. Respectively, each testbeds will. Use open source drivers for backward compatibility with the current WiFi technology based on the IEEE 802.11 standard. This approach uses a standard, non-cooperative physical layer since it is not possible to access the physical layer in commercial products.. Be based on software defined radio, allowing maximum flexibility in the implementation of a cooperative physical layer, a cooperative medium access control (MAC) layer as well as cross-layer design.Cooperative networking, where two or more active users in the network share their resources to jointly transmit their messages, provides resistance to fading, high throughput/low delay and reduced interference/low transmitted power. This infrastructure, leveraged in part by the WARP platform at Rice U, the ORBIT testbed at Rutgers U, and the CRAWDAD database at Dartmouth U, provides an open-access platform that will be used to build experimental deployable and scalable cooperative wireless networks, enabling current techniques to be moved beyond the current theoretical and simulation studies.The testbeds validate the feasibility of cooperative networking, enable platforms where new algorithms can be tested, and lead to new theory founded on more realistic assumptions.Broader Impacts: This first effort in implementing a fully cooperative network is expected to accelerate commercial developments in the field and impact current wireless standards. It facilitates a closer relationship with industry. Moreover, the infrastructure contributes to train students and service new courses.
