提案编号：CNS 07-08989 PI： 放大图片作者：Elza Bertoni，亨利L.; Panwar，Shivendra S.;机构：纽约理工大学 Brooklyn，NY 11201- 3840标题： 合作网络试验床 收款金额：30万美元项目建议：该项目建立两个互补的合作网络测试平台，以应对无线通信系统经常遭受的衰落和多径失真，以及多个用户在有限带宽上工作所造成的干扰。每个测试台将分别。使用开放源代码驱动程序，以向后兼容基于IEEE 802.11标准的当前WiFi技术。这种方法使用标准的非协作物理层，因为在商业产品中不可能访问物理层。基于软件无线电，在实现协作物理层、协作媒体访问控制（MAC）层以及跨层设计方面具有最大的灵活性。协作组网，即网络中的两个或多个活动用户共享其资源以联合传输其消息，提供抗衰落、高吞吐量/低延迟和减少干扰/低发射功率。Rice U的WARP平台、Rutgers U的ORBIT测试平台和达特茅斯U的CRAWDAD数据库部分地利用了该基础设施，该基础设施提供了一个开放访问平台，该平台将用于构建实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仿真研究。更广泛的影响：这是实现完全合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。它促进了与工业界更密切的关系。此外，基础设施有助于培训学生和服务新课程。

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.
