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

net - nbd: XORs在空中：实用无线网络编码奖0627021无线网络是不可或缺的；它们为移动性、城市范围的互联网连接、分布式传感和户外计算提供了手段。然而，当前的无线实现受到吞吐量的严重限制，不能扩展到密集的大型网络。本项目探索了一种显著提高无线网络吞吐量的新架构。除了转发报文外，路由器还对报文进行混合（即编码），以增加每次传输的信息含量。新的设计植根于网络编码理论。先前对网络编码的研究主要是理论性的。这个项目旨在把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，提供无线网络吞吐量的巨大改进，促进移动性，允许不需要节点协调的机会路由，并在恶意无线节点存在的情况下保持吞吐量增益。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.
