NeTS-NBD: XORs in the Air: Practical Wireless Network Coding

NeTS-NBD：空中XOR：实用无线网络编码奖0627021 Dina Katabi Muriel Medard无线网络是不可或缺的;它们提供了移动性、城市范围的互联网连接、分布式传感和户外计算的手段。 然而，当前的无线实现遭受吞吐量的严重限制，并且不能扩展到密集的大型网络。该项目探索了一种新的架构，可显著提高无线网络的吞吐量。除了转发数据包之外，路由器还混合（即，码）分组以增加每次传输的信息内容。 新的设计是植根于网络编码的理论。先前关于网络编码的工作主要是理论上的。该项目旨在将理论与实践联系起来;它解决了单播流量、动态和潜在突发流的常见情况，以及当前网络堆栈中网络编码集成所面临的实际问题。如果成功，该项目可以实现高吞吐量密集无线网络。具体来说，PI期望该项目产生新的协议，提供无线网络的吞吐量的大幅改善，促进移动性，允许机会路由没有节点协调，并保持吞吐量增益的恶意无线节点的存在。 研究结果将通过出版物、合作和教育过程传播给研究界和工业界。

NeTS-NBD: XORs in the Air: Practical Wireless Network CodingAward 0627021Dina Katabi Muriel MedardWireless networks are indispensable; they provide the means for mobility, city-wide Internet connectivity, distributed sensing, and outdoor computing. Current wireless implementations, however, suffer from severe limitations in throughput and do not scale to dense large networks. This project explores a new architecture that significantly increases the throughput of wireless networks. In addition to forwarding packets, routers mix (i.e., code) packets to increase the information content of each transmission. The new design is rooted in the theory of network coding. Prior work on network coding is primarily theoretical. This project aims to bridge theory with practice; it addresses the common case of unicast traffic, dynamic and potentially bursty flows, and practical issues facing the integration of network coding in the current network stack.If successful, this project can enable high-throughput dense wireless networks. Specifically, the PIs expect the project to produce new protocols that provide large improvements in the throughput of wireless networks, facilitate mobility, allow opportunistic routing without node-coordination, and maintain throughput gains in the presence of malicious wireless nodes. The results will be disseminated to the research community and industry via publications, collaborations, and the educational process.
