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

NETS-NBD：空中XOR：实用无线网络编码奖0627021Dina Katabi Muriel Medard无线网络是不可或缺的；它们为移动性、全市互联网连接、分布式传感和户外计算提供了手段。然而，当前的无线实施在吞吐量方面受到严重限制，并且不能扩展到密集的大型网络。该项目探索了一种可显著提高无线网络吞吐量的新架构。除了转发分组外，路由器还混合(即编码)分组以增加每次传输的信息内容。新的设计植根于网络编码理论。以前关于网络编码的工作主要是理论上的。该项目旨在理论与实践之间架起桥梁，解决单播流量、动态和潜在突发流量的常见情况，以及当前网络堆栈中网络编码整合所面临的实际问题。如果成功，该项目可以实现高吞吐量的密集无线网络。具体地说，PI预计该项目将产生新的协议，这些协议可以大幅提高无线网络的吞吐量，促进移动性，允许在没有节点协调的情况下进行机会路由，并在存在恶意无线节点的情况下保持吞吐量收益。结果将通过出版物、合作和教育过程向研究社区和行业传播。

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.
